Abstract (from CDS):

We report on the discovery of WASP-37b, a transiting hot Jupiter orbiting an mv= 12.7 G2-type dwarf, with a period of 3.577469±0.000011 d, transit epoch T0= 2455338.6188±0.0006 (HJD; dates throughout the paper are given in Coordinated Universal Time (UTC)), and a transit duration 0.1304+0.0018 –0.0017d. The planetary companion has a mass Mp= 1.80±0.17 MJ and radius Rp= 1.16+0.07–0.06RJ, yielding a mean density of 1.15+0.12–0.15ρJ. From a spectral analysis, we find that the host star has M{sstarf}= 0.925±0.120 M☉, R{sstarf}= 1.003 ±0.053 R☉, Teff= 5800±150 K, and [Fe/H] = -0.40±0.12. WASP-37 is therefore one of the lowest metallicity stars to host a transiting planet.
