11th BroadSky Workshop “Small Satellites, Big Possibilities” P A ST Stronger solar wid flux Stronger XUV flux Continuous CME flare Reactions upon these parameters are essentially important to know the early phase of the solar system Munetaka UENO
11th BroadSky Workshop “Small Satellites, Big Possibilities” Mapping the energy transportation by EUV slit imaging spectroscopy Most of the induced energy of the magnetosphere is cooled by the EUV radiation. Existence of the EUV radiation suggests a mysterious source of induced energy Current debates on the induced mechanism increase of density and temperature of the background ions injection of high energy ions Plasma torus neutral gas super-thermalized electrons ~40% ionization S, O ions 10100eV ~10% transport イオ io ~60% mysterious heating mechanism Examination of plasma torus using EUV spectroscopy → derive the electron temperature Time variation and time scale of the thermal structure → Strong constraint for the induced mechanism of the energetics of the rotating magnetosphere in Jupiter Munetaka UENO Ion/electron Coulomb’s scattering Background electrons a few - a few tens eV EUV radiation ~90% ~30% Delamere & Bagenal (2003)
