Ultraviolet C II and Si III Transit Spectroscopy and Modeling of the Evaporating Atmosphere of GJ436b
R. O. Parke Loyd, T. T. Koskinen, Kevin France +2
Hydrogen gas evaporating from the atmosphere of the hot-Neptune GJ436b absorbs over 50% of the stellar Ly emission during transit. Given the planet's atmospheric composition and…
Saturn Variable Thermosphere
Darrell F. Strobel, Tommi Koskinen, Ingo Mueller-Wodarg
Our knowledge of Saturns neutral thermosphere is far superior to that of the other giant planets due to Cassini Ultraviolet Imaging Spectrograph (UVIS) observations of 15 solar occ…
EUV-driven ionospheres and electron transport on extrasolar giant planets orbiting active stars
J. M. Chadney, M. Galand, T. T. Koskinen +4
The composition and structure of the upper atmospheres of Extrasolar Giant Planets (EGPs) are affected by the high-energy spectrum of their host stars from soft X-rays to EUV. This…
