Abstract (from CDS):

We report the discovery of HAT-P-27b, an exoplanet transiting the moderately bright G8 dwarf star GSC 0333-00351 (V = 12.214). The orbital period is 3.039586 ±0.000012 days, the reference epoch of transit is 2455186.01879±0.00054 (BJD), and the transit duration is 0.0705±0.0019 days. The host star with its effective temperature 5300±90 K is somewhat cooler than the Sun and is more metal-rich with a metallicity of +0.29±0.10. Its mass is 0.94 ± 0.04 M☉ and radius is 0.90+0.05_- 0.04R☉_. For the planetary companion we determine a mass of 0.660±0.033 MJ and radius of 1.038+0.077 _- 0.058RJ_. For the 30 known transiting exoplanets between 0.3 MJ and 0.8 MJ, a negative correlation between host star metallicity and planetary radius and an additional dependence of planetary radius on equilibrium temperature are confirmed at a high level of statistical significance.
