QPOs from Radial and Vertical Oscillation of Shocks in Advective Accretion Flows
Sandip K. Chakrabarti, K. Acharyya, D. Molteni
Abstract
We present results of several numerical simulations of two dimensional advective flows which include cooling processes. We show that the computed light curve is similar to the χ state in GRS 1915+105. The power density spectrum (PDS) also shows presence of QPOs near the break frequency.
