WASP-15


WASP-15 is a magnitude 11 star located about 1000 light-years away in the constellation Hydra.〔 The star, which is more massive, larger, hotter, and more luminous than the Sun, is also less metal-rich than the Sun. WASP-15 has one known planet in its orbit, WASP-15b; the planet is a Hot Jupiter with an anomalously high radius, a phenomenon which may be explained by the presence of an internal heat source.〔 The star was first observed by the SuperWASP program in 2006; future measurements in 2007 and 2008, as well as follow-up observations and analysis, eventually led to the discovery of WASP-15b using the transit method and Doppler spectroscopy.〔
==Observational history==

WASP-15 was first observed by the South African Astronomical Observatory, which coordinates the planet-searching SuperWASP program in the Southern Hemisphere (WASP-South), and was catalogued by its brightness and its coordinates in the sky. This information was captured first with one camera field between May 4, 2006 and July 17, 2006, and later again using two overlapping camera fields between January 31, 2007 to July 7, 2007 and from January 31, 2008 to May 29, 2008.〔
Data processing led to the acquisition of 24,943 data points that suggested that some body transited, or crossed in front of (and briefly dimmed), WASP-15 every 3.7520 days. Approximately eleven transits, full and partial, were observed. Use of the EulerCAM photometer at the La Silla Observatory's 1.2 m Leonhard Euler Telescope on March 29, 2008 provided further evidence for an exoplanet by better defining the transit's curve. Later, the CORALIE spectrograph (also on the Euler telescope) between March 6, 2008 and July 17, 2008 used Doppler spectroscopy to collect 21 radial velocity measurements. Analysis confirmed the presence of a planet that was later designated WASP-15b.〔
