2. Scientific Interests
Magnetosphere – Ionosphere – Thermosphere (MIT) coupling
Investigate how the solar wind influences planetary atmospheres
Solving the gas giant energy crisis
Magnetospheric physics
Low frequency magnetohydrodynamic (MHD) waves in giant planet magnetospheres
Saturn’s peculiar periodicities

3. Proposed work at ESAC Solving the gas giant energy crisis
Why is Jupiter’s atmosphere so hot?
Where does the extra heat come from?
Solar EUV alone; Strobel and Smith, 1973.
Galileo probe;
Seiff et al 1998
Caused by redistribution of heat from the interaction with Jupiter’s magnetosphere
