Io's volcanic control of Jupiter's extended neutral clouds
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 sodium directional feature: Evidence for ionospheric escape
TL;DR: In this paper, the authors present evidence that Io's sodium directional feature is produced by neutralization of pickup ions over the anti-Jovian hemisphere of Io, which is consistent with an ionospheric escape mechanism.

Io Hot Spots in 1991: Results from Europa Occultation Photometry and Infrared Imaging
TL;DR: In this article, the authors obtained infrared photometry of four of these events at the United Kingdom Infrared Telescope at wavelengths of 5.0 or 3.4 μm, in order to investigate the nature and distribution of volcanism on Io by observing the occultation of the volcanic hot spots by the limb of Europa.

Formation of Na-Containing Molecular Ions at Io
TL;DR: In this article, the charge exchange cross sections for forming NaX(+) are shown to be large for plasma torus ions colliding with NaX molecules in Io's corona, and two reactions are suggested as sources of NaX (+) and hence as the ultimate sources of the observed fast Na.

The Jovian sodium nebula: Two years of ground‐based observations
TL;DR: The 1000-R(sub J)-wide neutral sodium nebula of Jupiter has now been observed on four separate occasions from late 1989 to early 1992 as mentioned in this paper, and the observations have consisted of both low-dispersion spectroscopy and direct imaging.
