※Description:
The Galilean moons of Jupiter, Io, Europa, Ganymede and Callisto, have fascinating phenomena. For example, Io is one volcanically active moon playing an essential role in shaping the magnetospheric environment of Jupiter. In addition, Europa is suggested to have outgassing plume activities which could be associated with its subsurface ocean. We will study the chemical composition and distribution of the atmospheres and plumes of these small bodies using with radio observations (such as SMA and ALMA) coupling with numerical modelings (i.e., radiative transfer, exospheric model). This project will provide crucial information of the outgassing events of these small bodies by investigating the sources of the atmospheric species and their contribution to Jupiter’s magnetosphere. Our work will also provide complementary efforts to upcoming space missions, such as NASA’s Europa Clipper and ESA’s JUICE.
