Seasonal variation of Saturn's Lyman- brightness
P. Stephenson, T. T. Koskinen, Z. Brown +5
We examine Saturn's non-auroral (dayglow) emissions at Lyman- observed by the {Cassini/UVIS} instrument from 2004 until 2016, to constrain meridional and seasonal trends in the…
Fully coupled photochemistry of the deuterated ionosphere of Mars and its effects on escape of H and D
Eryn M. Cangi, Michael S. Chaffin, Roger V. Yelle +2
Although deuterium (D) on Mars has received substantial attention, the deuterated ionosphere remains relatively unstudied. This means that we also know very little about non-therma…
Compositional Measurements of Saturn's Upper Atmosphere and Rings from Cassini INMS
J. Serigano, S. M. Hörst, C. He +4
The Cassini spacecraft's last orbits directly sampled Saturn's thermosphere and revealed a much more chemically complex environment than previously believed. Observations from the…
Solar System Ice Giants: Exoplanets in our Backyard
Abigail Rymer, Kathleen Mandt, Dana Hurley +110
Future remote sensing of exoplanets will be enhanced by a thorough investigation of our solar system Ice Giants (Neptune-size planets). What can the configuration of the magnetic f…
Electron densities and alkali atoms in exoplanet atmospheres
Panayotis Lavvas, Tommi Koskinen, Roger V. Yelle
We describe a detailed study on the properties of alkali atoms in extrasolar giant planets, and specifically focus on their role in generating the atmospheric free electron densiti…
Thermal escape from extrasolar giant planets
T. T. Koskinen, P. Lavvas, M. J. Harris +1
The detection of hot atomic hydrogen and heavy atoms and ions at high altitudes around close-in extrasolar giant planets (EGPs) such as HD209458b imply that these planets have hot…
