Presentation details
» X-ray variability and viscous time scale at accretion disks
Presentation duration: 20 minutes
Presenter: Vadim Arefiev
We present analysis of nonperiodic variations of X-ray radiation from LMXBs. This variability is governed by diffusion propagation of density perturbations to main energy release zone near the accreting object. We show that the shape of X-ray power density spectra is sensitive to viscose time scale of the whole accretion disk.
