Polars:
energy balance revisited
€New measurements have been made of ~40 polars (60% of known systems) to examine the energy balance using
XMM-Newton which covers both hard and soft X-ray
bands and also the optical/UV
€Generally coverage of most of orbital; good fits achieved using stratified accretion column model
