Probing the Precession of the Inner Accretion Disk in Cygnus X-1

摘要: We show that changes in the orientation of inner accretion disk Cyg X-1 affect shape broad Fe Kα emission line emitted from this object, such a way eV-level spectral resolution observations (such as those will be carried out by Astro-E2 satellite) can used to analyze dynamics disk. present here potential diagnostic tool supported numerical simulations which few X-1, separated time, determine whether its actually precesses, and if so, period precession angle. This approach could also for similar studies other microquasar systems.
