Escape of hydrogen from the exosphere of Mars [PDF]

, 2016
After decades of exploration, the martian neutral hydrogen exosphere has remained poorly characterized. The first measurements of this layer by Mariner 6 and 7 revealed it to be optically thick in Lyman α emission, along with a characteristic temperature

Lyα Emissions from Titan’s Atmosphere and Exosphere

The Planetary Science Journal
From 2004 to 2017, the Cassini/UVIS instrument observed Titan’s Ly α airglow from Titan’s atmosphere and exosphere, helping to characterize Titan’s H population. Most Ly α observations remain unanalyzed. Using data from the T10 Titan flyby, we analyze Ly

Far-ultraviolet Flares and Variability of the Young M Dwarf AU Mic: A Nondetection of Planet C in Transit at Lyα

The Astronomical Journal
Atmospheric escape’s potential to shape the exoplanet population motivates detailed observations of systems actively undergoing escape. AU Mic is a young and active M dwarf hosting two close-in transiting sub- to Neptune-sized planets. Atmospheric escape

Exospheric Temperature of Venus

Exospheric Temperature of Venus
The local time dependence of the Cytherean exospheric temperature in the instantaneous heating rate model is calculated by solving the heat conduction equation. It is found that the differential heating by the solar ultraviolet radiation produces steep temperature gradients near terminator, mainly due to the low exospheric temperatures at the night ...
