Volcanic outgassing due to tidal heating is the ultimate source of a tenuous SO2 atmosphere around Jupiter's moon Io. The question of whether SO2 frost on the surface plays a part, and to what degree, in maintaining Io's atmosphere with the constant volcanic outgassing is still debated. It is believed that for a sublimation‐supported atmosphere, the primary atmosphere should collapse during eclipses by Jupiter, as the SO2 vapor pressure is strongly coupled to the temperature of the ice on the… 

Emission from volcanic SO gas on Io at high spectral resolution

An attempt to detect transient changes in Io’s SO2 and NaCl atmosphere

Sodium and Potassium Signatures of Volcanic Satellites Orbiting Close-in Gas Giant Exoplanets

Extrasolar satellites are generally too small to be detected by nominal searches. By analogy to the most active body in the solar system, Io, we describe how sodium (Na i) and potassium (K i) gas

ALMA Observations of Io Going into and Coming out of Eclipse

We present 1 mm observations constructed from Atacama Large (sub)Millimeter Array (ALMA) data of SO2, SO, and KCl when Io went from sunlight into eclipse (2018 March 20) and vice versa (2018

Io’s Atmosphere Silhouetted by Jupiter Lyα

We report results from a new technique for mapping Io’s SO2 vapor distribution. The Space Telescope Imaging Spectrograph (STIS) instrument on the Hubble Space Telescope observed Io during four

Io is the most volcanically-active object in the solar system. The moon ejects a tonne per second of sulphur-rich gases that fill the vast magnetosphere of Jupiter and drives million-amp electrical

MHD Modeling of the Plasma Interaction With Io's Asymmetric Atmosphere

Io's atmosphere, with an average equatorial column density of ≥1020 m−2, exhibits significant density variations with latitude and longitude. We apply a 3‐D magnetohydrodynamic model to investigate

ALMA Observation of SO2 Gas Originating from Io’s Volcanic Plume and Lava Areas

We detected the submillimeter spectrum of SO2 gas originating from volcanic plumes and lava areas in Jupiter’s moon Io by analyzing the ALMA archive data observed before and after ingress on 2018



Io's dayside SO2 atmosphere

Io's Atmospheric Response to Eclipse: UV Aurorae Observations

Comparisons to detailed simulations of Io's aurora indicate that volcanoes supply 1 to 3% of the dayside atmosphere, and far-ultraviolet aurora morphology reveals the influence of plumes on Io's electrodynamic interaction with Jupiter's magnetosphere.
