KOI2838 |
This system hosts a 0.7 Rearth planet candidate with a 4.8 day period. |
|
|
The Kepler data also revealed a 7.7 day false positive (Burke et al. |
KOI2014a |
|
2014). We detected a companion 4.04 Ks mags fainter than KOI2838 at a |
|
|
distance of 1".75. The estimated Kp mag of the companion is Kp = 18.5 |
|
|
(dKp = 5.0) and the approximate dilution correction is a 0.5% increase |
|
|
to the radius of the planet candidate. KOI 2838 does not display a |
|
|
significant source offset during transits. |
