Dynamical nature of GRS 1915+105 : Application of Two Component Flow |
|
Abstract |
Unique X-ray variabilities, sub-divided in 13 classes, of galactic black hole GRS 1915+105 are re-analysed. The analysis is based on the archival data of GRS 1915+105 observed with RXTE. Our analysis includes the dynamical study of timing and spectral features of 2 to 40 keV X-ray photons. The low energy photons (2 – 10 keV) originated from Keplerian disks, are inverse-comptonized by 'hot' electron of the inner part of the disk and thus produces high energy photons. The change in high energy photons to low energy photons with time is nothing but the change of disk flow and hence the disk structure. The X-ray variations of GRS 1915+105 are explained with the Two Component Advective Flow (TCAF) paradigm. |
