XRISM/Resolve observations of Hercules X-1: a pulsating, highly broadened Fe K emission line from the neutron star accretion column
New XRISM observations confirm a highly broadened, pulsating Fe K line from the accretion column of Hercules X-1 that varies with pulse phase and evolves with the 35-day precession cycle.
