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…

Revealing Callisto's Near Subsurface Thermophysical Properties with ALMA Calibration Data
Cole Meyer, Maria Camarca, Katherine de Kleer +3
Thermal images at different wavelengths probe varying subsurface depths of planetary bodies, and therefore can inform us about their compositions, thermophysical properties, and im…

A multi-frequency global view of Callisto's thermal properties from ALMA
Maria Camarca, Katherine de Kleer, Bryan Butler +5
We present thermal observations of Callisto's leading and trailing hemispheres obtained using the Atacama Large Millimeter/submillimeter Array (ALMA) at 0.87 mm (343 GHz), 1.3 mm (…
