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 $…
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…
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…
Sulphur dioxide in the mid-infrared transmission spectrum of WASP-39b
Diana Powell, Adina D. Feinstein, Elspeth K. H. Lee +70
The recent inference of sulphur dioxide (SO) in the atmosphere of the hot (1100 K), Saturn-mass exoplanet WASP-39b from near-infrared JWST observations suggests that phot…
Debris Disks can Contaminate Mid-Infrared Exoplanet Spectra: Evidence for a Circumstellar Debris Disk around Exoplanet Host WASP-39
Laura Flagg, Alycia J. Weinberger, Taylor J. Bell +21
The signal from a transiting planet can be diluted by astrophysical contamination. In the case of circumstellar debris disks, this contamination could start in the mid-infrared and…
Volatile Loss and Classification of Kuiper Belt Objects
R. E. Johnson, A. Oza, L. A. Young +2
Observations indicate that some of the largest Kuiper Belt Objects (KBOs) have retained volatiles in the gas phase, which implies the presence of an atmosphere that can affect thei…
