Issues
€This has been an extremely active field in the last 3
decades. Many scientists addressing the issues, large amount of
time devoted on observational facilities, large and small,
on ground and in-orbit
€Much is now understood about these systems, and many of the fundamental issues in these systems have been addressed (energy balance in Polars, disk-instabilities
in non-magnetics, accretion curtains in IPs)
€Mature field, which is developing around its boundaries:
ultra-compact
systems are an important and exciting
new
development
€However:
the effect of new facilities, particularly in the X-rays (XMM-Newton and Chandra) and UV (FUSE,
XMM-OM) is only now beginning to be felt, also greater access to 8m telescopes on the ground
Þ we can
still expect to learn a great deal
