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 1.75R 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 ± 0.06MJ and radius of 1.32 ± 0.05RJ, and orbits with a period of 3.16 days, WASP-48b has a mass of 0.98 ± 0.09MJ , radius of 1.67 ± 0.10RJ , 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±0.05MJ and radius of 1.42±0.03RJ , agreeing with values of 0.71±0.03MJ and 1.34±0.07RJ reported for HAT-P-30b.
