Methane release on Early Mars by atmospheric collapse and atmospheric reinflation [PDF]
, 2019 A candidate explanation for Early Mars rivers is atmospheric warming due to surface release of H$_2$ or CH$_4$ gas. However, it remains unknown how much gas could be released in a single event.

The impacts of coronal mass ejections on the space environments of Venus and Mars
地球与行星物理论评Coronal mass ejections (CME) are solar transients, and their impacts on the planets within the solar system have attracted considerable attention. As neighboring planets within the solar system, Venus and Mars are also directly and indirectly affected by

The atmospheric circulation of the super Earth GJ 1214b: Dependence on composition and metallicity [PDF]
, 2014 We present three-dimensional atmospheric circulation models of GJ 1214b, a 2.7 Earth-radius, 6.5 Earth-mass super Earth detected by the MEarth survey. Here we explore the planet's circulation as a function of atmospheric metallicity and atmospheric composition, modeling atmospheres with a low mean-molecular weight (i.e., H2-dominated) and a high mean ...

The Atmospheric Ghost Correction [PDF]
arXiv, 2021 While the presence of ghosts has been known for decades, the impact of these apparitions on remote sensing observations has gone unquantified, leaving atmospheric corrections susceptible to ghosting. In this work, we present the first spectral characterization of three common ghost types and provide a framework for incorporating these properties into ...
