Publications of the Astronomical Society of the Pacific, 128 (074401 - 074401. doi:10.1088/1538-3873/128/965/074401en_US
dc.description.abstractWe report the discovery of HATS-15 b and HATS-16 b, two massive transiting extrasolar planets orbiting evolved (∼10 Gyr) main-sequence stars. The planet HATS-15 b, which is hosted by a G9 V star (V = 14.8 mag), is a hot Jupiter with mass of 2.17 0.15  MJ and radius of 1.105 0.040  RJ, and it completes its orbit in about 1.7 days. HATS-16 b is a very massive hot Jupiter with mass of 3.27 0.19  MJ and radius of 1.30 0.15 ;  RJ it orbits around its G3 V parent star (V = 13.8 mag) in ∼2.7 days. HATS-16 is slightly active and shows a periodic photometric modulation, implying a rotational period of 12 days, which is unexpectedly short given its isochronal age. This fast rotation might be the result of the tidal interaction between the star and its planet.en_US
