18 Jan 2011 | | Abstract: | We report the discovery of HAT-P-27b, a transiting extrasolar planet orbiting
the moderately bright V=12.214 G8 dwarf star GSC 0333-00351, with period P =
3.039586 +/- 0.000012 d, transit epoch Tc = 2455186.01879 +/- 0.00054 (BJD),
and transit duration 0.0705 +/- 0.0019 d. The host star has a mass of 0.94 +/-
0.04 Msun, radius 0.90 +/- 0.04 Rsun, effective temperature 5300 +/- 90 K, and
metallicity [Fe/H] = +0.29 +/- 0.10. The planetary companion has a mass of
0.660 +/- 0.033 MJ and radius 1.038 +0.077 -0.058 RJ, yielding a mean density
0.73 +/- 0.13 g cm^{-3}. According to recent theoretical models, these
parameters are consistent with a 4 Gyr old planet having a 10 MEarth core. A
negative correlation between host star metallicity and planetary radius is
found at a 0.03% level of statistical significance for known transiting
exoplanets between 0.3 MJ and 0.8 MJ. | | Source: | arXiv, 1101.3511 | | Services: | Forum | Review | PDF | Favorites | |
