 In 2010 , a European science team investigated the star using the <unk> spectrograph and collected seventeen spectra of WASP @-@ 44 . From the spectra , radial velocity measurements were <unk> . Analysis of collected <unk> data ruled out the possibility that the detected radial velocity was caused by the blended spectrum of a spectroscopic binary star , supporting the possibility that the body orbiting WASP @-@ 44 was indeed a planet , designated WASP @-@ 44b .
