Abstract (from CDS):

Aims. We present the discovery and characterisation of the exoplanets WASP-113b and WASP-114b by the WASP surveys, SOPHIE and CORALIE.
Methods. The planetary nature of the systems was established by performing follow-up photometric and spectroscopic observations. The follow-up data were combined with the WASP-photometry and analysed with an MCMC code to obtain system parameters.
Results. The host stars WASP-113 and WASP-114 are very similar. They are both early G-type stars with an effective temperature of ∼5900K, [Fe/H]∼0.12, and logg∼4.1dex. However, WASP-113 is older than WASP-114. Although the planetary companions have similar radii, WASP-114b is almost four times heavier than WASP-113b. WASP-113b has a mass of 0.48M_Jup and an orbital period of ∼4.5-days; WASP-114b has a mass of 1.77M_Jup and an orbital period of ∼1.5days. Both planets have inflated radii, in particular WASP-113 with a radius anomaly of =0.35. The high scale height of WASP-113b (∼950km) makes it a good target for follow-up atmospheric observations.
