Description

We report the discovery of two transiting Neptunes by the HATSouth survey. The planet HATS-37Ab has a mass of 0.099 +- 0.042 MJ (31.5 +- 13.4 M) and a radius of 0.606 +- 0.016 RJ, and is on a P = 4.3315 day orbit around a V = 12.266 +- 0.030 mag, 0.843-+0.0120.017 M☉ star with a radius of 0.877-+0.0120.019 R☉. We also present evidence that the star HATS-37A has an unresolved stellar companion HATS-37B, with a photometrically estimated mass of 0.654 +- 0.033 M☉. The planet HATS-38b has a mass of...[Show more]
