 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 .
