Callisto from JWST: CO2-rich terrain on the leading hemisphere and global patterns of H2O ice
Maria Camarca, Katherine de Kleer, Richard J. Cartwright +5
We present maps of H2O, CO2, and a 4.57 um spectral feature across Callisto's surface observed using the James Webb Space Telescope (JWST). H2O ice was mapped by measuring band par…
Increasing science yield with a twilight observing program with the SCALES instrument at Keck
Isabel J. Kain, Carlos Alvarez, John M. O'Meara +13
While astronomical twilight closes the observing window for optical astronomers, the infrared sky remains dark even through sunrise, allowing IR astronomers to observe through twil…
Observed Latitudinal, Longitudinal and Temporal Variability of Io's Atmosphere Simulated by a Purely Sublimation Driven Atmosphere
A. -C. Dott, J. Saur, S. Schlegel +3
How much of Io's SO atmosphere is driven by volcanic outgasing or sublimation of SO surface frost is a question with a considerable history. We develop a time dependent sur…
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 $…
