We report the discovery of four transiting extrasolar planets (HAT-P-34b–HAT-P-37b) with masses ranging from 1.05 to 3.33 M_J and periods from 1.33 to 5.45 days. These planets orbit relatively bright F and G dwarf stars (from V = 10.16 to V = 13.2). Of particular interest is HAT-P-34b which is moderately massive (3.33 M_J), has a high eccentricity of e = 0.441 ± 0.032 at a period of P = 5.452654 ± 0.000016 days, and shows hints of an outer component. The other three planets have properties that are typical of hot Jupiters.

Additional Information:© 2012 The American Astronomical Society. Received 2011 December 23; accepted 2012 April 13; published 2012 June 11. Based in part on observations obtained at the W. M. Keck Observatory, which is operated by the University of California and the California Institute of Technology. Keck time has been granted by NOAO (A289Hr) and NASA (N167Hr and N029Hr). Based in part on data collected at the Subaru Telescope, which is operated by the National Astronomical Observatory of Japan. Based in part on observations made with the Nordic Optical Telescope, operated on the island of La Palma jointly by Denmark, Finland, Iceland, Norway, and Sweden, in the Spanish Observatorio del Roque de los Muchachos of the Instituto de Astrofisica de Canarias. HATNet operations have been funded by NASA grants NNG04GN74G and NNX08AF23G. We acknowledge partial funding of the HATNet follow-up effort from NSF AST-1108686. We acknowledge partial support also from the Keple rMission under NASA Cooperative Agreement NCC2-1390 (D.W.L. and PI). G.K. thanks the Hungarian Scientific Research Foundation (OTKA) for support through grant K-81373. This research has made use of Keck telescope time granted through NOAO (program A289Hr) and NASA (N167Hr and N029Hr). This paper uses observations obtained with facilities of the Las Cumbres Observatory Global Telescope. Data presented in this paper are based on observations obtained at the HAT station at the Submillimeter Array of SAO, and HAT station at the Fred Lawrence Whipple Observatory of SAO. The authors recognize and 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.
