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
The paper examines how magnetospheric plasma and thermal processes create, trap, and release molecular oxygen on the icy surfaces of Europa and Ganymede, explaining observed aurora…
Survival of satellites during the migration of a Hot Jupiter
Emeline Bolmont, Edward Galantay, Sergi Blanco-Cuaresma +2
We investigate the origin and stability of extrasolar satellites orbiting close-in gas giants, focusing on whether these satellites can survive planetary migration within a protopl…
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…
Doppler Shifted Transient Sodium Detection by KECK/HIRES
Athira Unni, Apurva V. Oza, H. Jens Hoeijmakers +12
We carried out the first high-resolution transit observations of the exoplanet WASP-49 Ab with Keck/HIRES. Upon custom wavelength calibration we achieve a Doppler RV precision of $…
Low-resolution Transit Spectroscopy of Three Hot Jupiters Using the 2m Himalayan Chandra Telescope
Athira Unni, Thirupathi Sivarani, Jayesh Goyal +3
Here, we present the low-resolution transmission spectroscopy of three giant planets using the Himalayan Faint Object Spectrograph Camera (HFOSC) on the 2m Himalayan Chandra Telesc…
