title = "HATS-22b, HATS-23b and HATS-24b: Three new transiting super-Jupiters from the HATSouth project",
abstract = "We report the discovery of three moderately high-mass transiting hot Jupiters from the HATSouth survey: HATS-22b, HATS-23b and HATS-24b. These planets add to the number of known planets in the *~2MJ regime. HATS-22b is a 2.74 ± 0.11MJ mass and 0.953+0.048-0.029 RJ radius planet orbiting a V = 13.455 ± 0.040 sub-solar mass (M* = 0.759 ± 0.019M⊙ R* = 0.759 ± 0.019 R⊙) K-dwarf host star on an eccentric (e = 0.079 ± 0.026) orbit. This planet's high planet-to-stellar mass ratio is further evidence that migration mechanisms for hot Jupiters may rely on exciting orbital eccentricities that bring the planets closer to their parent stars followed by tidal circularization. HATS-23b is a 1.478 ± 0.080MJ mass and 1.69 ± 0.24 RJ radius planet on a grazing orbit around a V = 13.901 ± 0.010 G-dwarf with properties very similar to those of the Sun (M* = 1.115 ± 0.054; R* = 1.145 ± 0.070). HATS- 24b orbits a moderately bright V = 12.830 ± 0.010 F-dwarf star (M* = 1.218 ± 0.036M⊙ R* = 1.194+0.066-0.041 R⊙). This planet has a mass of 2.39+0.21-0.12MJ and an inflated radius of 1.516+0.085-0.065 RJ.",

note = "Funding Information: The HATSouth network is operated by a collaboration consisting of Princeton University (PU), the Max Planck Institute f{\"u}r Astronomie (MPIA), the Australian National University (ANU) and the Pontificia Universidad Cat{\'o}lica de Chile (PUC). The station at Las Campanas Observatory (LCO) of the Carnegie Institute is operated by PU in conjunction with PUC, the station at the High Energy Spectroscopic Survey (H.E.S.S.) site is operated in conjunction with MPIA, and the station at Siding Spring Observatory (SSO) is operated jointly with ANU. Based in part on data collected at Subaru Telescope, which is operated by the National Astronomical Observatory of Japan. Also based in part on observations made with the MPG 2.2 m telescope at the ESO Observatory in La Silla. Development of the HATSouth project was funded by NSF MRI grantNSF/AST-0723074, operations have been supported byNASA grants NNX09AB29G and NNX12AH91H, and follow-up observations receive partial support from grant NSF/AST-1108686.

VS acknowledges support form BASAL CATA PFB-06. MR acknowledges support from FONDECYT postdoctoral fellowship 3120097. This work is based on observations made with ESO Telescopes at the La Silla Observatory. This paper also uses observations obtained with facilities of the Las Cumbres Observatory Global Telescope. Work at the Australian National University is supported by ARC Laureate Fellowship Grant FL0992131. We acknowledge the use of the AAVSO Photometric All-Sky Survey (APASS), funded by the Robert Martin Ayers Sciences Fund, and the SIMBAD data base, operated at CDS, Strasbourg, France. Operations at the MPG 2.2 m telescope are jointly performed by the Max Planck Gesellschaft and the European Southern Observatory. The imaging system GROND has been built by the high-energy group of MPE in collaboration with the LSW Tautenburg and ESO. We thank R{\'e}gis Lachaume for his technical assistance during the observations at the MPG 2.2 m telescope. We also thank Helmut Steinle and Jochen Greiner for supporting the GROND observations presented in this manuscript. We are grateful to P. Sackett for her help in the early phase of the HATSouth project.
