WASP-36 is a yellow main sequence star in the Hydra constellation.
Star characteristics
WASP-36 is a yellow main sequence star of spectral class G2, similar to the Sun.[4] It has an unconfirmed stellar companion with apparent magnitude 14.03.[5][6]
Planetary system
In 2010, the SuperWASP survey found the Hot Jupiter class planet WASP-36b using the transit method.[7] Its temperature was measured to be 1705±44 K.[8] The planetary transmission spectrum taken in 2016 has turned out to be anomalous: the planet appears to be surrounded by a blue-tinted halo that is too wide to be an atmosphere and may represent a measurement error.[9]
