A Scatter of Light from a Polarized World
Sloane J. Wiktorowicz, Pushkar Kopparla, Jiazheng Li +1
Many known exoplanets harbor clouds, which lead to degeneracies in spectroscopic models between particle composition and size. Polarimetry, however, provides independent assessment…
Volcanic Satellites Tidally Venting Na, K, SO2 in Optical & Infrared Light
Apurva V. Oza, Andrea Gebek, Moritz Meyer zu Westram +19
Recent infrared spectroscopy from the James Webb Space Telescope (JWST) has spurred analyses of common volcanic gases such as carbon dioxide (CO2), sulfur dioxide (SO2), alongside…
Hard X-ray Emission in AU Mic Flares: A Minor Contributor to Planetary Atmospheric Escape
Yifan Hu, Murray Brightman, Fabio Favata +7
Stellar flares are potent drivers of atmospheric evolution on orbiting exoplanets, primarily through extreme ultraviolet (EUV) and soft X-ray (XUV) irradiation. However, the contri…
Plasma and Thermal Processing Leading to Spatial and Temporal Variability of the Trapped O2 at Europa and Ganymede
Apurva V. Oza, Robert E. Johnson, Carl A. Schmidt +2
We describe the physical processes that affect the formation, trapping, and outgassing of O2 at Europa and Ganymede. Following Voyager measurements of their ambient magnetospheric…
Electron-induced chemistry and sputtering of volatile species from amorphous and crystalline water ice
Yogeshwar Nath Mishra, Sankhabrata Chandra, Murthy S. Gudipati +3
Electron irradiation of water-rich ices plays a significant role in initiating the chemical and physical processes on the surface of airless icy bodies in radiation environments su…
Hypotheses for near-surface exchange of methane on Mars
Renyu Hu, A. Anthony Bloom, Peter Gao +2
The Curiosity rover recently detected a background of 0.7 ppb and spikes of 7 ppb of methane on Mars. This in situ measurement reorients our understanding of the Martian environmen…
