KOI2421 |
The system hosts a 0.7 Rearth planet candidate with a 2.3 day orbit |
|
|
(Batalha et al. 2013). We detected two companions 0.42 and 2.62 Ks |
KOI2013a |
|
mags fainter than KOI 2421 at separations of 1".12 and 4".0, |
|
|
respectively. The closer companion is predicted to be Kp = 15.1 (dKp = |
|
|
0.7), the farther companion Kp = 17.8 (dKp = 3.5). Due to the similar |
|
|
brightness of the innermost companion and KOI2421, this system will |
|
|
require a significant dilution correction. If all light from the |
|
|
innermost companion is captured in the Kepler aperture and the planet |
|
|
orbits the target star, the planet radius measurement will need to be |
|
|
increased by 23% to account for dilution. KOI2421 does not exhibit a |
|
|
large source offset during transit, which lends support to the theory |
|
|
that the planet candidate orbits the target star, but the system |
|
|
should be inspected closely to confirm this. |
