Abstract

We report the discovery of HAT-P-30b, a transiting exoplanet orbiting the V = 10.419 dwarf star GSC 0208-00722. The planet has a period P = 2.810595 ± 0.000005 days, transit epoch T_c = 2455456.46561 ± 0.00037 (BJD), and transit duration 0.0887 ± 0.0015days. The host star has a mass of 1.24 ± 0.04M , radius of 1.21 ± 0.05R , effective temperature of 6304 ± 88K, and metallicity [Fe/H] = +0.13 ± 0.08. The planetary companion has a mass of 0.711 ± 0.028M _J and radius of 1.340 ± 0.065R _J yielding a mean density of 0.37 ± 0.05g cm^-3. We also present radial velocity measurements that were obtained throughout a transit that exhibit the Rossiter-McLaughlin effect. By modeling this effect, we measure an angle of λ = 735 ± 90 between the sky projections of the planet's orbit normal and the star's spin axis. HAT-P-30b represents another example of a close-in planet on a highly tilted orbit, and conforms to the previously noted pattern that tilted orbits are more common around stars with T _eff ≳ 6250K.
