HAT-P-30 follow-up photometry

Listed in IVOA Registry (Virtual Observatory)

We report the discovery of HAT-P-30b, a transiting exoplanet orbiting the V=10.419 dwarf star GSC 0208-00722.

Description

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+/-0.0015 days. The host star has a mass of 1.24+/-0.04M_{sun}_, radius of 1.21+/-0.05R_{sun}_, 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 {lambda}=73.5+/-9.0{deg} 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.
