Description
We report the discovery of HATS-2b, the second transiting extrasolar planet detected by the HATSouth survey. HATS- 2b is moving on a circular orbit around a V=13.6mag, K-type dwarf star (GSC 6665-00236), at a separation of 0.0230+/-0.0003AU and with a period of 1.3541-days. The planetary parameters have been robustly determined using a simultaneous t of the HATSouth, MPG/ESO 2.2m/GROND, Faulkes Telescope South/Spectral transit photometry, and MPG/ESO 2.2m/FEROS, Euler 1.2m/CORALIE, AAT 3.9m/CYCLOPS radial-velocity measurements.
