Abstract

We report the discovery from WASP-South of a new Jupiter-like extrasolar planet, WASP-16b, which transits its solar analog host star every 3.12 days. Analysis of the transit photometry and radial velocity spectroscopic data leads to a planet with R-p = 1.008 +/- 0.071 R-Jup and M-p = 0.855 +/- 0.059 M-Jup, orbiting a host star with R-* = 0.946 +/- 0.054 R-circle dot and M-* = 1.022 +/- 0.101M(circle dot). Comparison of the high resolution stellar spectrum with synthetic spectra and stellar evolution models indicates the host star is a near-solar metallicity ([Fe/H] = 0.01 +/- 0.10) solar analog (T-eff = 5700 +/- 150 K and log g = 4.5 +/- 0.2) of intermediate age (tau = 2.3(-2.2)(+5.8) Gyr).
