Io's SO2 and NaCl Wind Fields From ALMA

Alexander E. Thelen, Katherine de Kleer, Martin A. Cordiner +3

We present spatially resolved measurements of SO and NaCl winds on Io at several unique points in its orbit: before and after eclipse, and at maximum eastern and western elonga…

The Thermal Structure and Composition of Jupiter's Great Red Spot From JWST/MIRI

Jake Harkett, Leigh N. Fletcher, Oliver R. T. King +15

Jupiter's Great Red Spot (GRS) was mapped by the James Webb Space Telescope (JWST)/Mid-Infrared Instrument (4.9-27.9 micron) in July and August 2022. These observations took place…

Redshifted Sodium Transient near Exoplanet Transit

Apurva V. Oza, Julia V. Seidel, H. Jens Hoeijmakers +21

Neutral sodium (Na I) is an alkali metal with a favorable absorption cross section such that tenuous gases are easily illuminated at select transiting exoplanet systems. We examine…

Short-Timescale Spatial Variability of Ganymede's Optical Aurora

Zachariah Milby, Katherine de Kleer, Carl Schmidt +1

Ganymede's aurora are the product of complex interactions between its intrinsic magnetosphere and the surrounding Jovian plasma environment and can be used to derive both atmospher…

Europa's HO: Temperature Insensitivity and a Correlation with CO

Peiyu Wu, Samantha K. Trumbo, Michael E. Brown +1

HO is part of Europa's water-ice radiolytic cycle and a potential source of oxidants to Europa's subsurface ocean. However, factors controlling the concentration of this cr…

LBT SHARK-VIS Observes a Major Resurfacing Event on Io

Al Conrad, Fernando Pedichini, Gianluca Li Causi +18

Since volcanic activity was first discovered on Io from Voyager images in 1979, changes on Io's surface have been monitored from both spacecraft and ground-based telescopes. Here,…

Isotopic evidence of long-lived volcanism on Io

Katherine de Kleer, Ery C. Hughes, Francis Nimmo +4

Jupiter's moon Io hosts extensive volcanism driven by tidal heating. The isotopic composition of Io's inventory of volatile elements, including sulfur and chlorine, reflects its ou…

Detection of a 2.85 micrometer Feature on 5 Spinel-rich Asteroids from JWST

Jonathan Gomez Barrientos, Katherine de Kleer, Bethany L. Ehlmann +2

Ground-based observations of `Barbarian' L-type asteroids at 1 to 2.5-m indicate that their near-infrared spectra are dominated by the mineral spinel, which has been attributed…

Observations of Titan's Stratosphere During Northern Summer: Temperatures, CH3CN and CH3D Abundances

Alexander E. Thelen, Conor A. Nixon, Martin A. Cordiner +11

Titan's atmospheric composition and dynamical state have previously been studied over numerous epochs by both ground- and space-based facilities. However, stratospheric measurement…

Atacama Large Aperture Submillimeter Telescope (AtLAST) Science: Planetary and Cometary Atmospheres

Martin A. Cordiner, Alexander E. Thelen, Thibault Cavalié +26

The study of planets and small bodies within our Solar System is fundamental for understanding the formation and evolution the Earth and other planets. Compositional and meteorolog…

Mass supply from Io to Jupiter's magnetosphere

L. Roth, A. Blöcker, K. de Kleer +24

Since the Voyager mission flybys in 1979, we have known the moon Io to be both volcanically active and the main source of plasma in the vast magnetosphere of Jupiter. Material lost…

Subsurface Thermophysical Properties of Europa's Leading and Trailing Hemispheres as Revealed by ALM

A. E. Thelen, K. de Kleer, M. Camarca +4

We present best-fit values of porosity -- and the corresponding effective thermal inertiae -- determined from three different depths in Europa's near-subsurface (~1-20 cm). The por…

Revealing Callisto's carbon-rich surface and CO2 atmosphere with JWST

Richard J. Cartwright, Geronimo L. Villanueva, Bryan J. Holler +18

We analyzed spectral cubes of Callisto's leading and trailing hemispheres, collected with the NIRSpec Integrated Field Unit (G395H) on the James Webb Space Telescope. These spatial…
