General:
How do OB stars produce X-rays at all? WhatÕs the connection between
their massive winds and their X-ray emission?
Specific:
WhatÕs the nature of wind instabilites and shocks in
normal hot
stars? Can this (class of)
model(s) work?
What role do magnetic fields play in hot stars and their
X-ray emission?
(e.g. do B stars have coronae? How can young hot stars be so hot and bright in
X-rays? How can hot stars with extreme X-ray
properties be understood?)
