Abstract (from CDS):

We report the discovery of WASP-13b, a low-mass M_p=0.46^+ 0.06^_–0.05M_J transiting exoplanet with an orbital period of 4.35298 ±0.00004 days. The transit has a depth of 9mmag, and although our follow-up photometry does not allow us to constrain the impact parameter well (0<b<0.46), with radius in the range R_p∼1.06-1.21R_J the location of WASP-13b in the mass-radius plane is nevertheless consistent with H/He-dominated, irradiated, low core mass and core-free theoretical models. The G1V host star is similar to the Sun in mass (M_*=1.03^+0.11_–0.09M_☉) and metallicity ([M/H]=0.0±0.2), but is possibly older (8.5^+5.5_–4.9Gyr).
