Lava Lakes on Io: crust age and implications for thermal output
Alessandro Mura, Rosaly M. C. Lopes, Federico Tosi +12
Recent observations by the JIRAM instrument onboard NASA's Juno mission have confirmed that many of Io's volcanic hot spots are active lava lakes, characterized by a colder central…
Observations of Loki Patera by Juno during close flybys
Alessandro Mura, JIRAM-Io team
We used data from the Juno spacecraft to investigate both the spatial and temporal properties of Loki Patera on Io, acquired in two infrared bands between December 2022 and April 2…
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…
JIRAM Observations of Volcanic Flux on Io: Distribution and Comparison to Tidal Heat Flow Models
M. Pettine, S. Imbeah, J. Rathbun +6
Juno has allowed clear, high-resolution imaging of Io's polar volcanoes using the Jovian Infrared Auroral Mapper (JIRAM) instrument. We have used data from JIRAM's M-band (4.78 um)…
