HAT-P-16b: A 4 M _J Planet Transiting a Bright Star on an Eccentric Orbit
We report the discovery of HAT-P-16b, a transiting extrasolar planet orbiting the V = 10.8 mag F8 dwarf GSC 2792-01700, with a period P = 2.775960 ± 0.000003 days, transit epoch T_c = 2455027.59293 ± 0.00031 (BJD^(10)), and transit duration 0.1276 ± 0.0013 days. The host star has a mass of 1.22 Â...
