KOI2904 |
This system hosts a 1.2 Rearth planet with a 16.4 day period (Burke et |
KOI2014a |
|
al 2014). We detected a companion 2.74 J mags and 2.58 Ks mags fainter |
|
|
than KOI2904 at a separation of 0".68. Using the J-Ks to Kp-Ks color- |
|
|
color conversion from Howell et al. (2012), we predict that the Kp mag |
KOI2012a |
|
of the companion is Kp = 15.8 (dKp = 3.1) if the star is a dwarf or |
|
|
Kp = 15.9 (dKp = 3.2) if the star is a giant. KOI 2904 has also been |
|
|
observed with speckle imaging using DSSI on WIYN and the companion was |
|
|
detected with mag differences of 2.83 mag at 692 nm and 2.77 mag at |
|
|
880 nm. The estimated dilution correction for this system is 3% |
|
|
assuming that the planet orbits the target star and that all of the |
|
|
light from the companion is captured in the Kepler aperture. KOI2904 |
|
|
does not display a significant source offset during transit. |
