The light curve for exoplanet WASP-14b in Bootes depicted above is one of the latest (and most massive) transitting exoplanets, having being announced in June/2008, and represents the fourteenth discovery by the WASP (Wide Angle Search for Planets) team. WASP-14b is characterized with a whopping mass 7.725 times that of Jupiter while its radius is equivalent to 1.259 Jupiter radii, thus making this exoplanet one of the densest discoveries to-date. WASP-14b requires 183.6 minutes to transit its parent star at a depth of 10.2 mmag or 1.02%. The parent star, GSC 1482:882, is an F5V star estimated to have a mass of 1.319 solar masses, a radius equivalent to 1.297 solar radii, a temperature of 6,475° K and to lie at a distance of 570 light-years away with a visual magnitude of 9.75. Further details regarding WASP-14 and WASP-14b are available in the paper published by the discovery team led by Y.C. Joshi et al here.
