An attempt to detect transient changes in Io's SO2 and NaCl atmosphere
L. Roth, J. Boissier, A. Moullet +15
Io's atmosphere is predominately SO2 sustained by a combination of volcanic outgassing and sublimation. The loss from the atmosphere is the main mass source for Jupiter's large mag…
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…
JWST molecular mapping and characterization of Enceladus' water plume feeding its torus
G. L. Villanueva, H. B. Hammel, S. N. Milam +18
Enceladus is a prime target in the search for life in our solar system, having an active plume likely connected to a large liquid water subsurface ocean. Using the sensitive NIRSpe…
Europa's Lyman- emissions from HST/STIS observations
L. Roth, K. D. Retherford, J. Saur +13
An image of Lyman- (Ly) emission from Europa obtained with the Hubble Space Telescope Space Telescope Imaging Spectrograph (HST/STIS) has previously provided the first evid…
Study of the atmospheric effects of energetic particle precipitations on giant planets with HWO
J-Y. Chaufray, W. Dunn, L. N. Fletcher +6
UV auroral emissions from giant planets are produced by extra-atmospheric energetic particles interacting with an atmosphere. They have been observed on Jupiter, Saturn and Uranus…
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…
Composition and thermal properties of Ganymede's surface from JWST/NIRSpec and MIRI observations
D. Bockelee-Morvan, E. Lellouch, O. Poch +21
JWST NIRSpec IFU (2.9-5.3 mu) and MIRI MRS (4.9-28.5 mu) observations were performed on both the leading and trailing hemispheres of Ganymede with a spectral resolution of ~2700. R…
The RATT PARROT: serendipitous discovery of a peculiarly scintillating pulsar in MeerKAT imaging observations of the Great Saturn-Jupiter Conjunction of 2020. I. Dynamic imaging and data analysis
O. M. Smirnov, B. W. Stappers, C. Tasse +11
We report on a radiopolarimetric observation of the Saturn-Jupiter Great Conjunction of 2020 using the MeerKAT L-band system, initially carried out for science verification purpose…
