Star characteristics edit
WASP-36 is a yellow main sequence star of spectral class G2, similar to the Sun.[5] It has an unconfirmed stellar companion with apparent magnitude 14.03.[6][7]
Planetary system edit
In 2010, the SuperWASP survey found the Hot Jupiter class planet WASP-36b using the transit method.[8] Its temperature was measured to be 1705±44 K.[9] 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.[10]
Planetary dayside temperature measured in 2020 is 1440+150
−160 K.[11]
