High Quality Content by WIKIPEDIA articles! WASP-44 is a G-type star in constellation Cetus that has the Jupiter-size planet WASP-44b in orbit. The star is slightly less massive and slightly smaller than the Sun; it is also slightly cooler, but is more metal-rich. The star was observed by SuperWASP, an organization in search of planets, starting in 2009; manual follow-up observations used WASP-44`s spectrum and measurements of its radial velocity led to the discovery of the transiting planet WASP-44b. The planet and its star were presented along with WASP-45b and WASP-46b on May 17, 2011 by a team of scientists testing the idea that Hot Jupiters tend to have circular orbits, an assumption that is made when the orbital eccentricity of such planets are not well-constrained.
