APH00011kd - dips

  • andrei_Gabi by andrei_Gabi

    Found some possible transits at:
    quarter 12-1 days 3 and 7.25 +
    quarter 12-3 days 25.25 and 28.5

    i have checked on https://archive.stsci.edu/kepler/planet_candidates.html and
    http://exoplanetarchive.ipac.caltech.edu/cgi-bin/TblView/nph-tblView?app=ExoTbls&config=cumulative and
    http://oldtalk.planethunters.org/search and couldn't find the Kepler id 5729682 with a planet candidate.

    Sadly i can't seem to find other dips in the other quarters.

    Day 25.25 in Q12-3 at BKJD 1093.75 is a well known glitch.

    I see. Thank you very much.

    I couldn't find references about this KID. But what do you mean when you say that it is well a well known glitch ? are you referring to this light curve or this configuration has been observed in other light curves as well ?

    Is there a way for me to differentiate this glitches from "good" transits ? Hmmm, if the other transits are real, then i should be able to approximate the objects radius / mass, right ? So the glitch, if a real transit, should have similar characteristics to the other transits, right ?

    Anyhow, how about the other dips ?

    Thank you

    Thank you very much, i have started reading the topic but sadly i can't seem to be able to see the pictures or graphs. I have also found your inputs there. The info stored in the old talk part of the site is much more rich than i have initially thought.

    I didn't even thought that what i was seeing was a glitch. Now i will take everything with a grain of salt (or more grains).

    Some glitches seem straight forward (an abnormal minimum in a dip or a single dip out of nowhere). Bu i have much more to read and many more examples to see.

    (edit. Not online abnormal dips, but also "flares" for very bright stars. hmmm)

    Thank you again zoo3hans
