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…

Characterising exoplanets and their environment with UV transmission spectroscopy

L. Fossati, V. Bourrier, D. Ehrenreich +36

Exoplanet science is now in its full expansion, particularly after the CoRoT and Kepler space missions that led us to the discovery of thousands of extra-solar planets. The last de…

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…
