KID 4581084 maybe P=185.02 days, starting at 677.04, duration 12.3 hours, depth 0.0006, R=0.49 R_Earth (!). This is my smallest candidate so far, the star is only 0.183 R_sol, so this is a bit speculative of course.

KID 2569995 maybe a PC with P=80.8x d starting at 1309.11 BKJD, 3 obviously similar signals and a 4th, which is somehow different/hidden

Dear JKD

yes, KID 2569995 has P=80.872 days, but MAST gives R_star=1.6 R_sol, which gives an estimate R_planet=22 R_Earth, which is too large for a planet, so I assume it's an EB, or rather contamination by one, since it is classified as "InCat=False" in the Kepler EB catalog http://keplerebs.villanova.edu/

KID 6268411 maybe single transit at 576.88, duration 20.6 hours, depth 0.0033, R=1.1 R_Earth estimate. The star is small, with a radius of 0.189 R_sol, mass 0.166 M_sol, temp 3214 K. Kian Jin Planetary Calculator gives then an estimate of a=11.7 au, P around 98 years. Too cold for comfort...

KID 6277788 maybe single transit at 1425.0, duration 20.0 hours, depth 0.0017, R_planet 5.2 R_Earth estimate. The star has radius 1.146 R_sol, mass 1.17 M_sol, temp 6509 K, 15.121 mag. This gives an estimate of P=1033 days, temp planet about 210 K (maybe still in the habitable zone).

Trinary

KID 7108433 is marked as an EB.

A minimal TTV can be detected.

However, it is obviously an EB with a third object around.

Single signal at S =1246.655 BKJD, Duration =3.9234 hrs, Depth ~14.2% and a marginal signal-shoulder at 1183.10 BKJD

Likely a Trinary

Dear JKD

yes, KID 7108433 is an interesting system. Maybe we have a secondary eclipse of the additional star at BKJD 1239.96, duration about 3.9 hours, depth 0.0149.

7108433

Unfortunately it turns out the the features are NOT visible in the SAP_FLUX data, so it seems it could be contamination of some sort. Tom Jacobs and Saul Rappaport took the trouble to investigate this star further to gether with Tamas Borkovits.

KID 8519065 looks like a transit at S=323.90 BKJD, Duration min.18.6 hrs, Depth min.1.4%

KID 8844362 pot. PC at S=1403.84 BKJD, Duration ~22.06 hrs, Depth =0.6%

KID 9838424 pot. PC at S=1572.01 BKJD, Duration ~4.90 hrs, Depth ~0.1%

KID 9843294 pot. PC at S=1572.73 BKJD, Duration ~3.43 hrs, Depth ~0.14%

KID 8844362 is too large for a PC, R_star = 28.4 * R_sol.

Posted January 25, 2017 4:18 PM

by zoo3hans in response to JKD's comment.

KID 9838424 looks possible. Maybe P=80.33 days, starting at 1331.03, duration 3-4 hours, depth about 0.0014, U-shaped. Possibly strong TTV's.

KID 6460812 P=0.5002 days, starting at 1274.26, duration 3.9 hours, depth 0.0022, 2.9 R-Earth estimate. Maybe a "corona-burner" or binary or contamination by a BGEB.

KID 7467076 maybe long transit at 1442.57, duration 86.3 hours, depth 0.0017, 13.1 R_Earth estimate. Since the star is R_star = 2.875 R_sol, we have a planet candidate with P=25.5 years, 11 au from the star, a bit similar to our Jupiter.

KID 8153568 , EB with interesting pulsations. P=3.6071431 days. KOI 6051.

KID 8561192 looks very similar to KID 8153568 , but has a somewhat sorter period. P=2.7425932 days. KOI 5544.

KID 10403228 it looks like an EB eclipse at 744.85, duration 42.2 hours, depth 0.045, 7.2 R_Earth estimate, but could be a PC instead. It is marked as "InCat=False" in the Kepler EB catalog. It could just be contamination of course.

KID 10456779 Maybe transit at 712.97, duration 4.9 hours, depth 0.0049, 1.05 R_Earth estimate. A bit speculative of course with such a small body.

A new Kepler data release should happen during this week. Will this be the final data release?

A new Kepler data release!

The new KOI hosts have KOI numbers between 7621 and 8297.

~160 of those new KOIs are considered candidates. The rest are considered false positives.

Note:

http://archive.stsci.edu/kepler/missing_lc.html

More than 50 previously unprocessed light curves from Kepler's original field have been released. Processing algorithms missed them before.

@zoo3hans are these found by randomly putting in KIC values, or are these stars targeted because they have missing data from multiple quarters?

Posted June 27, 2017 5:05 PM

by ProtoJeb21 in response to JKD's comment.

I may have found an orbital period for your candidate around KIC 9838424. With LcViewer your transit has a duration of ~3.4 hours, and a similar transit is found at epoch 1274.58895. This gives the planet a year of 297.438925 days, sigma 3.56. Looks like an ice giant at the outer edge of the system's habitable zone. Host star is unusually hot (5370*K) for its size (0.57 solar radii).
