EPIC 210908968 - APH0000vc8

• by davidbundy77

  EPIC 210908968 - APH0000vc8 two possible similiar looking transits:

  BKJD 2244.91 - 2245.16 (coincides with jump in raw flux, so maybe just a glitch)

  BKJD 2284.56 - 2284.71 (spotted by Layman Sterms on Talk)

  Depths about 0.0006. No nearby stars. Estimating from the colours, star has spectrum of roughly K4V.

  I agree with David, transit at BKJD 2245.03 and 2284.63, which would give a period around 39.6 days. Depth about 0.0003. If the classification of the star is indeed K4V, I would then get a 1.2 R_Earth planet at 0.2 au from its star and a temp around 347 K. It would be in the habitable zone of its star, although a bit on the warm side.

  Thanks for the info. That is a little warmer than my rough estimate. Using Kian's Calculator with 0.7 x R_Sol (Kepler Fit) makes the planet 1.5 x R_Earth with an equilibrium temperature of 407 K.
