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.^[5] It has an unconfirmed stellar companion with apparent magnitude 14.03.^[6]^[7]

Planetary system

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]
