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. Dre2014
