Impact of Quasi-Periodic Oscillations on the energy spectrum
Abstract
The presence of QPOs in the PDS of x-ray binaries is quite ubiquitous and is often model as a structure orbiting in the disk. While we have been using timing and PDS to determine the presence and explore the possible origin of QPOs, they are, up to now, absent of the spectral analysis. Here we are using a simple analytical model to mimic the hot structure of several QPO model to determine if ATHENA will be able to distinguish between them.
