YAN Dongdong, GUO Jianheng and Xing Lei from Yunnan Observatories of the Chinese Academy of Sciences, collaborating with Huang Chenliang from University of Arizona, deduced that there is an expanding and escaping thermal neutral hydrogen atmosphere around hot Jupiter WASP-121b by simulating the optical transmission spectrum (Hα) of this exoplanet. The study was published in The Astrophysical Journal Letters. Source: https://phys.org/news/2021-02-optical-band-probe-atmosphere-hot.html…

Evidence for substance at liquid-gas boundary on exoplanet WASP-31b
One of the properties that make a planet suitable for life is the presence of a weather system. Exoplanets are too far away to directly observe this, but astronomers can search for substances in the atmosphere that make a weather system possible. Researchers from SRON Netherlands Institute for Space Research and the University of Groningen have now found evidence on exoplanet…
A ‘super-puff’ planet like no other
The core mass of the giant exoplanet WASP-107b is much lower than what was thought necessary to build up the immense gas envelope surrounding giant planets like Jupiter and Saturn, astronomers at Université de Montréal have found. Source: https://phys.org/news/2021-01-super-puff-planet.html…
