Abstract

We report the discovery and characterization of four transiting exoplanets by the HATNet survey. The planet HATP- 50b has a mass of 1.35 MJ and radius of 1.29 RJ, and orbits a bright (V = 11.8 mag) M = 1.27 M, R = 1.70 R star every P = 3.1220 days. The planet HAT-P-51b has a mass of 0.31MJ and radius of 1.29 RJ, and orbits a V = 13.4 mag, M = 0.98 M, R = 1.04 R star with a period of P = 4.2180 days. The planet HAT-P-52b has a mass of 0.82MJ and radius of 1.01 RJ, and orbits a V = 14.1mag, M = 0.89 M, R = 0.89 R star with a period of P = 2.7536 days. The planet HAT-P-53b has a mass of 1.48 MJ and radius of 1.32 RJ, and orbits a V = 13.7 mag, M = 1.09 M, R = 1.21R star with a period of P = 1.9616 days. All four planets are consistent with having circular orbits and have masses and radii measured to better than 10% precision. The low stellar jitter and favorable Rp/R∗ratio for HAT-P-51 make it a promising target for measuring the RossiterMcLaughlin effect for a Saturnmass planet.
