A Low‐Mass Planet with a Possible Sub‐Stellar‐Mass Host in Microlensing Event MOA‐2007‐BLG‐192
We report the detection of an extrasolar planet of mass ratio q ~ 2 x 10^(-4) in microlensing event MOA-2007-BLG-192. The best fit microlensing model shows both the microlensing parallax and finite source effects, and these can be combined to obtain the lens masses of M = 0.060 (+0.028 -0.021) …
