€Infalling material is forced to follow the
magnetic field lines
€Gas is initially in free-fall but then it
encounters a shock front
€Shock converts kinetic energy into thermal energy (bulk
motion into random motion) Þ temperature
increases to ~50 keV
€Velocity drops by 1/4 and density increases by 4
€Material radiates by cyclotron and bremstrahlung and gradually settles
on white dwarf
