Abstract

We report the discovery and characterization of four transiting exoplanets by the HATNet survey. The planet HAT-P-50b has a mass of 1.35 M_J and radius of 1.29 R_J, 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 0.31 M_J and radius of 1.29 R_J, 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 0.82 M_J and radius of 1.01 R_J, and orbits a V = 14.1 mag, 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 M_J and radius of 1.32 R_J, and orbits a V = 13.7 mag, M = 1.09 M_⨀, R = 1.21 R_⨀ 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 R_p/R_* ratio for HAT-P-51 make it a promising target for measuring the Rossiter–McLaughlin effect for a Saturn-mass planet.

HATNet operations have been funded by NASA grants NNG04GN74G, NNX08AF23G, and NNX13AJ15G. Follow-up of HATNet targets has been partially supported through NSF grant AST-1108686. G. Á. B, Z. C. and K.

T. acknowledges partial support from NASA grant NNX14AB83G. We acknowledge partial support also from the Kepler Mission under NASA Cooperative Agreement NCC2-1390 (D.W.L., PI). Data presented in this paper are based on observations obtained at the HAT station at the Submillimeter Array of SAO, and the HAT station at the Fred Lawrence Whipple Observatory of SAO. The authors wish to acknowledge the very significant cultural role and reverence that the summit of Mauna Kea has always had within the indigenous Hawaiian community. We are most fortunate to have the opportunity to conduct observations from this mountain. This research has made use of Keck telescope time granted through NOAO (program A245Hr) and NASA (N154Hr, N130Hr). This research was made possible through the use of the AAVSO Photometric All-Sky Survey (APASS), funded by the Robert Martin Ayers Sciences Fund.
