Abstract:
We report the discovery by the WASP transit survey of two new highly
irradiated giant planets. WASP-64 b is slightly more massive
(1.271±0.068MJup) and larger (1.271±0.039RJup) than Jupiter,
and is in very-short (a=0.02648±0.00024AU,
P=1.5732918±0.0000015-days) circular orbit around a V=12.3 G7-type
dwarf (1.004±0.028M☉, 1.058±0.025R☉,
Teff=5500±150K). Its size +0.059 is typical of hot Jupiters with
similar masses. WASP-72 b has also a mass a bit higher than Jupiter's
(1.461-0.056MJup) and orbits very close (0.03708±0.00050AU,
P=2.2167421±0.0000081days) to a bright (V=9.6) and moderately
evolved F7-type star (1.386±0.055M☉, 1.98±0.24R☉,
Teff=6250±100K). Despite its extreme irradiation
(∼5.5x109erg/s/cm2), WASP-72 b has a moderate size
(1.27±0.20RJup) that could suggest a significant enrichment in
heavy elements. Nevertheless, the errors on its physical parameters
are still too high to draw any strong inference on its internal
structure or its possible peculiarity.
