Questions we’d like to address with high-resolution X-ray spectroscopy
How do OB stars produce X-rays
at all? What’s the connection between their massive winds
and their X-ray emission?
What’s 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?)
