Exploring the structure and composition
of Io's atmosphere with (sub)mm observations
Jupiter's moon Io, that has been
recognized as the most volcanically active object in the Solar system, holds a
tenuous atmosphere that feeds a plasma torus in orbit around Jupiter, thus
requiring the presence of a significant and continuous gas source to replenish
itself. This atmosphere has been extensively observed in the past 20 years, and
in particular at (sub)mm wavelengths, which allow to investigate its
composition, temperature, spatial distribution and dynamics.
I will present the most significant advances achieved in the understanding of
the nature of Io's atmosphere and the mechanisms shaping it, focusing on
results obtained with (sub)mm single-dish facilities (IRAM-30m, APEX) and
interferometers (IRAM-Plateau de Bure, SMA).
