WASP-36 is a G-type main-sequence star about 1,230 light-years away in the Hydra constellation.
خصائص النجم
WASP-36 is a yellow main sequence star of spectral class G2, similar to the Sun.[7] It has a candidate stellar companion with apparent magnitude 14.03,[8][9] seemingly confirmed in 2019 using Gaia DR2 data.[10]
النظام الكوكبي
In 2010, the SuperWASP survey found the hot Jupiter class planet WASP-36b using the transit method.[11] Its temperature was measured to be 1705+44−{{{2}}} K.[12] 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.[6]
The planetary dayside temperature measured in 2020 is 1440+150−160 K.[13]
