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 Rp∼1.06-1.21RJ 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). Description: WASP-13 was monitored with the SuperWASP-N Camera (La Palma) from 2006 November 27 to 2007 April 1.
