WASP-36 is a yellowmain sequencestar in theHydraconstellation.

Star characteristics

[edit]

WASP-36 is a yellowmain sequence star of spectral class G2, similar to theSun.[5] It has an unconfirmed stellar companion withapparent magnitude 14.03.[6][7]

Planetary system

[edit]

In 2010, theSuperWASP survey found theHot Jupiter class planet WASP-36b using thetransit method.[8] Its temperature was measured to be 1705±44K.[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]
