Abstract
We report the detection of WASP-35b, a planet transiting a metal-poor ([Fe/H] = -0.15) star in the Southern hemisphere, WASP-48b, an inflated planet which may have spun-up its slightly evolved host star of 1.75 R-circle dot in the Northern hemisphere, and the independent discovery of HAT-P-30b/WASP-51b, a new planet in the Northern hemisphere. UsingWASP, RISE, Faulkes Telescope South, and TRAPPIST photometry, with CORALIE, SOPHIE, and NOT spectroscopy, we determine that WASP-35b has a mass of 0.72 +/- 0.06 M-J and radius of 1.32 +/- 0.05 R-J, and orbits with a period of 3.16 days, WASP-48b has a mass of 0.98 +/- 0.09 M-J, radius of 1.67 +/- 0.10 R-J, and orbits in 2.14 days, while HAT-P-30b/WASP-51b, with an orbital period of 2.81 days, is found to have a mass of 0.76 +/- 0.05 M-J and radius of 1.42 +/- 0.03 R-J, agreeing with values of 0.71 +/- 0.03 M-J and 1.34 +/- 0.07 R-J reported for HAT-P-30b.
