 WASP @-@ 13 is a sunlike G @-@ type star located in the Lynx constellation . Measurements taken by FIES and SOPHIE did not constrain the mass , radius , or age well ; however , a later 2011 study using the Liverpool Telescope better @-@ constrained those parameters . The star 's mass is estimated at 1 @.@ 09 times the mass of the Sun , its radius at 1 @.@ 559 times that of the Sun , and its density at 0 @.@ 288 time 's the Sun 's density . These characteristics are re @-@ defined taking limb darkening into account . The star 's metallicity , which is measured by iron content , is placed roughly at [ Fe / H ] = 0 , similar to that of the Sun . Also , the star 's estimated effective temperature is 5826 K , slightly warmer than the Sun .
