KOI2879 |
This system was reported to have a 1.4 Rearth planet with a 0.3 day |
|
|
period (Burke et al. 2014), but this signal has been found to be a |
KOI2014a |
|
false positive. Our ARIES observations revealed a companion 0.37 J |
|
|
mags and 0.27 Ks mags fainter than KOI 2879 at a distance of 0".423. |
|
|
Using the J-Ks to Kp-Ks color-color conversion from Howell et al. |
|
|
(2012), we predict that the Kp mag of the companion is Kp = 13.8 |
KOI2012a |
|
(dKp = 1.1) if the star is a dwarf or Kp = 13.9 (dKp = 1.2) if the |
|
|
star is a giant. If any additional planet candidates are detected |
|
|
around KOI2879, their radii will need to be increased by roughly 17% |
|
|
to account for the additional light in the aperture. |
