TLDR
In this article, dramatic changes in the brightness and shape of Jupiter's extended sodium nebula are found to be correlated with the infrared emission brightness of Io, and they conclude that silicate volcanism on Io controls both the rate and the means by which sodium escapes from Io's atmosphere.About:

STIS Coronagraphic Imaging of Fomalhaut: Main Belt Structure and the Orbit of Fomalhaut b
TL;DR: In this paper, the authors presented new optical coronagraphic data of Fomalhaut b obtained with HST/STIS in 2010 and 2012, and the two epochs of Space Telescope Imaging Spectrograph (STIS) photometry exclude optical variability greater than 35%.

Cassini UVIS observations of the Io plasma torus. IV. Modeling temporal and azimuthal variability
TL;DR: In this article, the authors presented a model of the remarkable temporal and azimuthal variability of the Io plasma torus observed during the Cassini encounter with Jupiter, where the authors postulate the existence of two azimated variations in the number of superthermal electrons in the torus: a primary variation with a period of 10.07 h and a secondary variation that remains fixed in System III longitude.

Composition of jovian dust stream particles

TL;DR: In this paper, the mass spectra of jovian stream particles were used to determine the chemical composition of particles, and the results imply that the vast majority (>95%) of the observed stream particles originate from the volcanic active jovians satellite Io from where they are sprinkled out far into the Solar System.

Brightening event seen in observations of Jupiter’s extended sodium nebula
TL;DR: Jupiter's sodium nebula has been observed to show variations in its brightness due to the volcanic activity on Io as mentioned in this paper, and the brightness increased by three times during this enhancement, while the D-line brightness had been stably faint and dim until January 2015, but it showed a distinct enhancement from February through March 2015.

Io's heat flow from infrared radiometry: 1983–1993
TL;DR: In this paper, the authors report the following results from a decade of infrared radiometry of Io: (1) the average global heat flow is more than approx. 2.5 W/sq.m, large warm (less than or equal to 200 K) volcanic regions dominate the global heat flows, smal high-temperature (greater than or = 300 K) 'hotspots' contribute little to the average heat flow, thermal anomalies on the leading hemisphere contribute about half of the heat flow and a substantial amount of heat is radiated during Io's night, high

Io on the eve of the galileo mission
TL;DR: Io, the innermost of Jupiter's large moons, is one of the most unusual objects in the Solar System as discussed by the authors, which produces a global heat flux 40 times the terrestrial value, producing intense volcanic activity and a global resurfacing rate averaging perhaps 1 cm yr−1.

Three‐dimensional plasma simulation of Io's interaction with the Io plasma torus: Asymmetric plasma flow
TL;DR: In this paper, a three-dimensional, stationary, two-fluid plasma model for electrons and one ion species was developed to understand the local interaction of Io's atmosphere with the Io plasma torus and the formation of Io ionosphere.

Volcanically emitted sodium chloride as a source for Io's neutral clouds and plasma torus
TL;DR: The detection of NaCl in Io's atmosphere is reported; it constitutes only ∼0.3% when averaged over the entire disk, but is probably restricted to smaller regions than SO2 because of its rapid photolysis and surface condensation.
