Abstract (from CDS):

Using the WASP transit survey, we report the discovery of three new hot Jupiters, WASP-68 b, WASP-73 b and WASP-88 b. The planet WASP-68 b has a mass of 0.95±0.03MJup, a radius of 1.24–0.06+0.10RJup, and orbits a V=10.7 G0-type star (1.24±0.03M, 1.69–0.06+0.11R, Teff=5911±60K) with a period of 5.084298±0.000015-days. Its size is typical of hot Jupiters with similar masses. The planet WASP-73 b is significantly more massive (1.88–0.06+0.07MJup) and slightly larger (1.16–0.08+0.12RJup) than Jupiter. It orbits a V=10.5 F9-type star (1.34–0.04+0.05M, 2.07–0.08+0.19R, Teff=6036±120K) every 4.08722±0.00022-days. Despite its high irradiation (∼2.3x109erg/s/cm2), WASP-73 b has a high mean density (1.20–0.30+0.26ρJup) that suggests an enrichment of the planet in heavy elements. The planet WASP-88 b is a 0.56±0.08MJup hot Jupiter orbiting a V=11.4 F6-type star (1.45±0.05M, 2.08–0.06+0.12R, Teff=6431±130K) with a period of 4.954000±0.000019-days. With a radius of 1.70–0.07+0.13RJup, it joins the handful of planets with super-inflated radii. The ranges of ages we determine through stellar evolution modeling are 4.5-7.0Gyr for WASP-68, 2.8-5.7Gyr for WASP-73 and 1.8-4.3Gyr for WASP-88. The star WASP-73 appears to be significantly evolved, close to or already in the subgiant phase. The stars WASP-68 and WASP-88 are less evolved, although in an advanced stage of core H-burning.
