KOI2754 This system hosts a 0.7 Rearth planet candidate with a 1.3 day period
(Burke et al. 2014). Our ARIES observations revealed a companion 2.11 KOI2014a
J mags and 1.65 Ks mags fainter than KOI2754 at a 0".763 separation.
The predicted Kp mag of the companion star is Kp = 15.3 (dKp = 3.0)
if the star is a dwarf and Kp = 15.2 (dKp = 2.9) if the star is a
giant. The companion star was also detected in the WIYN speckle
imaging acquired with DSSI. The companion is 3.12 mag. fainter than
KOI2754 at 692 nm and 2.56 mags fainter at 880 nm. Assuming that the
planet orbits the target star and that all of the light from the
companion is captured in the Kepler aperture, then the planet radius
should be increased by 3% to account for dilution. KOI2754 does not
exhibit a significant source offset during transit. Dre2014
