KOI2298 |
This system contains a 1 Rearth planet candidate with a 16.7 day orbit |
|
|
(Batalha et al. 2013). NEXSci also reports a 0.8 Rearth false positive |
KOI2013a |
|
with a 31.8 day period. We detected a companion 1.3 Ks mags fainter |
|
|
than KOI2298 at a distance of 1".47. The companion is expected to have |
|
|
Kp = 15.2 (dKp = 1.4), indicating that contamination may lead to a |
|
|
significant underestimate of the planet radius. In the simple |
|
|
approximation that all light from the companion star is captured in |
|
|
the Kepler aperture, the radius estimate for the planet should be |
|
|
increased by 13% to account for the dilution if indeed the planet |
|
|
orbits the target star and the companion has Kp = 14.9. However, the |
|
|
companion may be the same object identified ~1" away from KOI2298 in a |
|
|
HIRES guider image. The estimated brightness contrast from the HIRES |
|
|
image is three mags, which implies companion is red enough that the |
|
|
dilution correction might be only a 3% change to the planet radius |
