Kinematically Resolving the Fe K Complex in Her X-1: The Accretion Disk and Ionized Wind Across X-ray Eclipses
Koh Sakamoto, Teruaki Enoto, Peter Kosec +8
We present XRISM/Resolve spectroscopy of Her X-1 across three X-ray eclipses observed in September 2024, resolving its iron K complex through the ingress, mid-eclipse, and egress p…

XRISM/Resolve observations of Hercules X-1: vertical structure and kinematics of the disk wind
Peter Kosec, Laura Brenneman, Erin Kara +11
X-ray binary accretion disk winds can carry away a significant fraction of the matter transferred from the companion and hence strongly affect the accretion flow and the long-term…
