Just more notes and observations from the C14 MAST data or earlier..
Re 248672683 from Ivan's and Hans Martin's lists: a nice transit as mentioned, but the star seems fairly large here for this depth of transit to be planetary (~40.76Re at 2.47 RSun). So maybe an early K-type giant or subgiant star here based on Huber's values, but a main sequence binary is also possible. Also nearby 248672544 at ~37 arcsecs has this transit as well (more blended in) which adds to the stellar transit case.

Re 201637208 from Ivan's list: this target appears to be a slightly eccentric binary with one heavily spotted binary component and flares.

Re 248584439 from Ivan and Hans Martin's lists: appears to be a white dwarf system as targeted by three K2 programs, and possibly also one with a companion to explain the regular flares or outbursts every 15.5 to 17 days. Also the nearby small dwarf's light curve (201805043 only 7.11 arcsecs away) looks contaminated by these same events, but does not seem to be a companion if the distance estimates are correct.

EPIC 248651022 is a likely multi-planet system that both @Dolorous_Edd and @ajamyajax have reported on well before I stumbled across the system in my 15th C14 work group. Using the highly uncertain parameters on ExoFOP I estimated the three planets to be 2.59, 2.95, and 4.52 R_Earth with equilibrium temperatures of 2063, 1579, and 1364 K. With this data, the innermost candidate looked to potentially be a large terrestrial COSSN (Closely-Orbiting Scorched Sub-Neptune). However, the star appears to be much smaller than the predicted ~1.8 R_Sun estimate on ExoFOP, mainly due to the transits of all three candidates lasting no more than 2.0-2.5 hours. EPIC 248651022 could be smaller than ajamyajax’s estimates of ~0.99 R_Sun, or the planets are just grazing the star. New planetary radii are 2.16, 1.87, and 2.96 R_Earth. More analysis is likely needed to determine the actual sizes of the star and its three planets.

Ok, what are your stellar radius and mass estimates then? I took the low range of a G9V 0.91 MSun dwarf from the colors on record. This also worked with my other period and duration estimates for these PCs. Also considering the 5544K Teff, 1.80 RSun, and 0.99 MSun from Huber et al, it doesn't seem likely this star is much smaller than that. But I'd like to see your reasoning if you have something else.

in response to ajamyajax's comment.
I haven't estimated any stellar parameters on my own. Since your estimates seem more reliable, I'm assuming that all three candidates are on grazing orbits to explain their short transit durations. This is quite similar to Kepler-409b, whose transits last only about 2 hours even though it too orbits a Sun-like star. Also, the new equilibrium temperatures I calculated for the planets using your estimated parameters are 1549, 1186, and 1024 Kelvin (for semi-major axes of 0.024633, 0.042063, and 0.0563278 AU). The innermost planet may not be a COSSN, but once I figure out how to use TTVFast I can figure out how massive the planets are and get a general idea of their compositions. Right now I predict that the inner planet would be a mainly terrestrial planet with a hydrogen envelope containing 0.5-10% of the planet's total mass, giving it a density somewhere between 5 and 1.5 g/cm^3.

Fair enough. I should mention, if you use them, that my quick G-F type size estimates (that we often see if not M-dwarfs) tend to be on the low side because I do not account for reddening etc. So if you get slightly longer durations in your transit observations, go with those with confidence.

Thanks, that's quite helpful. I found the J-H and H-K values for the potential red dwarf EPIC 220221272, which are 0.573 for J-H and 0.251 for H-K. The only two stars with similar values are the M4V dwarfs Kepler-445 and Kepler-446. EPIC 220221272's J-H and H-K values fall right between those of Kepler-445 and Kepler-446, indicating that its ExoFOP parameters are relatively accurate, if not slightly higher than its true parameters. If the mass and radius of EPIC 220221272 are also between those of the two Kepler dwarfs, then the star is likely about 0.20 R_Sun and 0.225 M_Sun. If the temperature remains the same at 3551 K, and the stellar parameters I calculated are correct, then the 5 likely planets are now 0.703, 0.690, 0.693, 0.809, and 1.326 R_Earth with equilibrium temperatures of 491, 398, 341, 301, and 269 K.

Back to Campaign 14 stuff: there’s this potential red dwarf called EPIC 248616368 that appears to have a 2.2 R_Earth planet orbiting every 25 days on the inner edge of the system’s habitable zone. However, the transit duration was unusually long at over 8 hours, suggesting that the host star could be much larger. Using the strategy employed by @ajamyajax I found EPIC 248616368’s J-H value to be 0.646 and its H-K value to be 0.213. Both of these are quite similar to the large M-dwarf Kepler-45. This makes EPIC 248616368 likely to be about the same size, somewhere between 0.55 and 0.60 R_Sun. However, not only is the planet candidate now non-habitable, its long transit durations are still left unexplained.

Another interesting find: EPIC 248731669, has three Super-Earths orbiting every 2.62, 14.05, and 21.96 days. The outermost planet is about 1.31 R_Earth with an equilibrium temperature of 281 K. The star's J-H and H-K values are 0.627 and 0.232, so it could be similar in size to the previous stars I mentioned, but I'm not too sure. On ExoFOP it's listed as being 0.313 R_Sun and 0.349 M_Sun with a temperature of 3750 K.

Re 248616368 from Hans Martin's and ProtoJeb's lists: the duration seems to be twice as long as expected in this ragged LC data fit, so a grazing binary eclipse seems like the best guess here. Maybe one star is 0.4RSun and the other closer to a brown dwarf in size. An outside chance might be an exoplanet with a ringed system (Saturn's rings are about 2.35X larger than the radius of the planet). Another less likely possibility is the M-dwarf stellar parameters are incorrect and this is a distance giant or subgiant star. We do see longer duration transits around those stars is why I mention that. And contamination from a nearby binary also a possibility with planet depth transits and always a consideration.

Re 248651022 follow-up: the star here can make a real difference in the composition of the planets (and they likely are), so a closer look at this... First a 3.897 logg value on ExoFOP seems to indicate a giant with 1.8 RSun, but the transit durations appear to be short enough for a main sequence dwarf instead. Although even if a ms dwarf the narrowing in the star size range still an issue because it could decide if these planets are rocky or smaller gas giants. Another source for clues is the UCAC4 catalog which has B and V magnitude values of 13.248 and 12.494 respectively. B-V and a table lookup below suggests a G4V star (if a dwarf) about 0.9 MSun, 1.1 RSun. These could also support somewhat larger planets, so since some of these seem more favorable in VESPA a few of my program estimates are below. But terrestrial planets are fine too. The good news is that both of the first two period calcs with different star and planet radii types have low False Positive Probabilities in my VESPA runs here, combined with the least-favorable odds p3 chart shown. Even if this candidate individually less probable, the chances of a planet transit are still ok when in an MPC configuration which as we know is very favorable for planets. Also this p3 planet transit is more v-shaped as shown and probably high impact which could explain the FPP differences.

Great job, especially with pinning down the radius of EPIC 248651022.01 to a mere 2% error margin. I'm under the assumption that the FPP you found for it and 248651022.02 are enough to get them validated, right?
I'm not too sure how 248651022.03 could be an eclipsing binary without throwing the inner two planets out of the system or into the star. My best guess for the V-shaped dip is that it's caused by grazing transits, meaning that if 248651022.03 is a planet, it may be significantly larger than expected.
Also, what are HEBs and BEBs (Blended Eclipsing Binaries)?

in response to ProtoJeb21's comment.
Thanks, but my radius estimates are always +/- something. And VESPA is often used for validation, but other's results could be different if they use different constraints, aperture ranges and other run-time settings than I did. So we'll see what ends up in a paper on this system, hopefully anyway. 😃
Edit: but yes, this is very likely a three-planet system and other tests should show similar results.
Also I believe that BEB = Background Eclipsing Binary and HEB = Hierarchical Eclipsing Binary, meaning three or more stars that are gravatationally bound and could be the source of any given transit, by probability in the target region anyway.

Two potential long-period circumbinary planets around a pair of M-dwarfs. The first is a likely Super-Neptune taking >80.4 days to orbit the pair; the second is a possible cold Super-Earth identified by one potential transit event. Both of these candidates are outside the outer limit of the habitable zone.

Hi ProtoJeb,
Hans Martin (zoo3hans) also spotted these transits back in the c14 raw cadence and agree with you this could be a circumbinary system! Will post more when I can, and hope you do also.

I recently noticed something weird with the 1.35 R_Earth transit-like event. The light curve shows a very shallow drop in brightness lasting about 12 hours, with the transit taking place right in the middle. I’m not too sure if this is just a coincidence of having a transit and an example of stellar variability happening at the same time, or if this suggests the candidate (if a legitimate planet) has a system of rings.

@ajamyajax there’s an extremely likely hot Super-Earth orbiting the Sun-like star EPIC 248656172. The host star is one of the brightest K2 stars, with a visual magnitude of 9.334, making it a great target for follow up observations. However, it has odd J-H and H-K magnitude values of 0.22 and 0.029, and I’m very unsure how large the star actually is. Is it closer in size to the Sun, or is it something like an F-class main sequence star or a G/F subgiant? I hope it isn’t too much larger, because this could be an excellent system for investigating hot rocky Super-Earth exoplanets, like Kepler-93b. If the star is significantly larger, so will the planet, and it would likely be a Mini-Neptune instead.

I think your stellar variability idea could be right for the possible rocky planet transit here. And with two small M-dwarfs it could difficult to see and confirm such a longer period transit. As you mentioned, any planet would need to a fair distance away from the gravitationally unstable region around a binary to maintain a stable orbit.
And from a quick check I didn't see any smaller rocky planets confirmed for circumbinary systems, so it is possible most if not all planets around multiple star systems must form near or past the frost line where any rocky material ends up composing only the inner core of a gas giant.
The good news is I think, that even my model center transit circular orbit with estimated sizes (also with the necessary combined masses) puts this possible gas giant transit a fair distance from these two stars. Even a shorter duration of about 3.6 hours suggests an orbit about 243 days if transiting the slightly larger dwarf and maybe 475 days if transited the smaller star.
More work is needed here though, including the answer to this question (which of these binary components the possible gas giant has probably transited) and as you mentioned also what the masses of these two stars are. Let's see what we can figure out.
Semi-Major Axis a (A.U.) = 0.601
Radius (R_Sun) = 0.25
Mass (M_Sun)= 0.49
Period ~= 243.29614 days
Duration ~= 3.6002 hours
Duration in BKJD ~= 0.15 daysSemi-Major Axis a (A.U.) = 0.94
Radius (R_Sun) = 0.2
Mass (M_Sun)= 0.49
Period ~= 475.16407 days
Duration ~= 3.6002 hours
Duration in BKJD ~= 0.15 daysFor Reference this period ~= 1.3 years

Re 248656172 from ProtoJeb's mention and Hans Martin's list: yes I think a wider range in the color estimates make this star classification more difficult to determine. Simbad has an F8 spectral type, J-H a F7, and my B-V math suggests maybe an F3. About the shortest duration I can fit is around 4.4 hours which means a larger star and possible giant or a binary transit instead of a planet. But the Teff should be hotter for an F-type star, which could be why Huber et al. have a Sun-size stellar estimate. So bottom line is can't constrain these stellar parameters any better than the fairly wide range of estimates on record just yet.

The combined luminosity of the EPIC 248868569 pair is about 0.013 L_sun, so with both potential orbital periods you found the gas giant candidate is extremely cold; 110 K (-262 F) at its warmest and 90 K (-298 F) at its coldest. This is the right temperature range for liquid methane to pool on the surface of its moons, if it has any.
Using the second transit’s duration of about 6.3 hours, the second candidate has an orbital period of either 1,302.74 days (3.57 years) if transiting the primary or 2,544.43 days (6.97 years) if transiting the secondary. It would have a semi major axis between 1.84 and 2.88 AU, and a temperature between 63 K (-344 F) and 50 K (-370 F), cold enough to freeze methane.

Well, we will see but I don't think this possible CB planet would be that far away. If the Teff value of 3577K is near correct, the combined masses should be in the 0.5x MSun range or larger in my view. But perhaps this is smaller, as you suggest.
Also I call every large planet a "gas giant" because even cold Neptune's atmosphere is nearly all hydrogen and helium, but technically these are "ice giants" because even methane is frozen as you mentioned.

Re 201663913 from your lists: alas, this target is complicated by several dips that are also in the LC of a very close star (epic 201663879 at 9.49 arcsecs) and maybe another target as well. So those could be bgeb contamination, glitches, or even artifacts. The other possible transits seem rather blended-in and could be planetary but might be difficult to fit and get positive fpp results from vespa. The stellar estimates also vary quite a bit so this light blending just another little complication here. And this image from Aladin Lite in SDSS9 coloration with the nearby extended epics labeled as well (galaxies with epics also just for interest's sake) but none of those light curves seem to have these events.

EPIC 248435473 is now confirmed with six planets, one of which is a sub-Earth in an eccentric orbit that brings it within the habitable zone during its apoapsis. There’s also a companion star with a candidate Warm Saturn.
