Abstract

We report the discovery of WASP-26b, a moderately over-sized Jupiter-mass exoplanet transiting its 11.3-mag early-G-type host star (1SWASP J001824.70-151602.3; TYC 5839-876-1) every 2.7566 days. A simultaneous fit to transit photometry and radial-velocity measurements yields a planetary mass of 1.02 plusmn 0.03 M$_Jup$ and radius of 1.32 plusmn 0.08 R$_Jup$. The host star, WASP-26, has a mass of 1.12 plusmn 0.03 M$_⊙$ and a radius of 1.34 plusmn 0.06 R$_⊙$ and is in a visual double with a fainter K-type star. The two stars are at least a common-proper motion pair with a common distance of around 250 plusmn 15 pc and an age of 6 plusmn 2 Gy. RV and photometric data are only available in electronic form at the CDS via anonymous ftp to cdsarc.u-strasbg.fr (130.79.128.5) or via http://cdsarc.u-strasbg.fr/viz-bin/qcat?J/A+A/520/A56
