X-ray Diagnostics and Their Relationship to Magnetic Fields

X-ray Diagnostics and Their Relationship to Magnetic Fields. David Cohen Swarthmore College. If we understand the physical connection between magnetic fields in massive stars and X-rays, we could use X-ray observations to identify magnetic massive stars.
