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
