Vertical Temperature Structure in Io's Atmosphere from ALMA SO Observations
Timothy N. Proudkii, Katherine de Kleer, Imke de Pater +4
The structure of Io's atmosphere is controlled by competing processes, from volcanic outgassing and sublimation to radiative cooling and plasma heating. Yet, the lack of an observa…
Satellites and small bodies with ALMA: Insights into Solar System formation & evolution
Katherine de Kleer, Michael E. Brown, Martin Cordiner +1
Our understanding of the formation and evolution of planetary systems has made major advances in the past decade. This progress has been driven in large part by the Atacama Large M…
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…
Zonal winds in Titan's middle atmosphere from a stellar occultation observed with Keck adaptive optics
Theresa C. Marlin, Eliot F. Young, Katherine de Kleer +9
We present spatially resolved Keck/NIRC2 images of a stellar occultation by Titan on September 5, 2022 and compare them to predictions from concurrent ALMA observations and a suite…
Revealing Io's Surface using JWST-NIRISS Aperture Masking Interferometry and Neural Network Deconvolution
J. Sanchez-Bermudez, I. dePater, A. Conrad +6
Io is one of Jupiter's largest moons and the most volcanically active body in the Solar System. Its very active surface has hot spots produced by volcanic eruptions popping up at s…
Detection of New Auroral Emissions at Io and Implications for Its Interaction with the Plasma Torus
Zachariah Milby, Katherine de Kleer, Carl Schmidt
We observed Io's optical aurora in eclipse on six nights between 2022 and 2024 using Keck I/HIRES. Spectra revealed 13 new auroral emissions not identified previously, tripling the…
