XRISM resolve observation 300065010

Object

Cyg_X-3

Abstract

We propose a 40 ks (minimal)/80 ks (ideal) observation of the unique and enigmatic high mass X-ray binary (HMXB) Cyg X-3. The iron line region in the Cyg X-3 spectrum contains hints of the dynamical effects of the black hole in this system. Improved measurements of the iron line radial velocity curve can be used to refine mass estimates for the black hole. In the soft state
