Questions we’d like to
address with high-resolution X-ray
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?)
What is the correct shock physics and radiation hydrodynamics at the interface between colliding winds?
(e.g. how important is radiative braking? Hydrodynamic instabilities?)
