Abstract

We report the discovery of three new transiting extrasolar planets orbiting moderately bright (V = 11.1, 11.7, and 12.4) F stars. The planets HAT-P-39b through HAT-P-41b have periods of P = 3.5439 days, 4.4572 days, and 2.6940 days, masses of 0.60 M_J, 0.62 M_J, and 0.80 M_J, and radii of 1.57 R_J, 1.73 R_J, and 1.68 R_J, respectively. They orbit stars with masses of 1.40 M_☉, 1.51 M_☉, and 1.51 M_☉, respectively. The three planets are members of an emerging population of highly inflated Jupiters with 0.4 M_J < M < 1.5 M_J and R > 1.5 R_J.

Additional Information:© 2012 American Astronomical Society. Received 2012 July 13; accepted 2012 August 30; published 2012 October 9. 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 (A201Hr, A289Hr, and A284Hr), NASA (N049Hr, N018Hr, N167Hr, N029Hr, N108Hr, and N154Hr), and the NOAO Gemini/Keck time-exchange program (G329Hr). Based in parton 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. Based in part on observations obtained with facilities of the Las Cumbres Observatory Global Telescope. HATNet operations have been funded by NASA grants NNG04GN74G, NNX08AF23G, and SAO IR&D grants. J.H. acknowledges partial support from NSF grant AST-1108686. G. Á .B., Z.C., and K.P. acknowledge partial support from NASA grant NNX09AB29G. G.T. acknowledges partial support from NASA grant NNX09AF59G. We acknowledge partial support also from the Kepler mission under NASA Cooperative Agreement NCC2-1390 (PI: D.W.L.). 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 (A201Hr, A289Hr, and A284Hr), NASA (N049Hr, N018Hr, N167Hr, N029Hr, N108Hr, and N154Hr), and the NOAO Gemini/Keck time-exchange program (G329Hr). This paper presents 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. This paper uses observations obtained with the facilities of the Las Cumbres Observatory Global Telescope. The Byrne Observatory at Sedgwick (BOS) is operated by the Las CumbresObservatory Global Telescope Network and is located at the Sedgwick Reserve, a part of the University of California Natural Reserve System. 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 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. Finally, we thank the referee for a rapid and helpful report which improved the quality of this paper.
