Correlations between X-ray Spectral and Timing Characteristics in Cyg X-2
Lev Titarchuk, Sergey Kuznetsov, Nikolai Shaposhnikov
Correlations between the quasi-periodic oscillations (QPOs) and the spectral power-law index have been reported for a number of black hole candidate sources and for four neutron st…
How To Distinguish Neutron Star and Black Hole X-ray Binaries? Spectral index and Quasi-Periodic Oscillation Frequency Correlation
Lev Titarchuk, Nickolai Shaposhnikov
Recent studies have revealed strong correlations between 1-10 Hz frequencies of quasiperiodic oscillations (QPOs) and the spectral power law index of several Black Hole (BH) candid…
The Bursting Behavior of 4U 1728-34: Parameters of a Neutron Star and Geometry of a NS-disk system
Nickolai Shaposhnikov, Lev Titarchuk, Frank Haberl
We analyze a set of Type I X-ray bursts from the low mass X-ray binary 4U 1728 -34, observed with Rossi X-ray Timing Explorer (RXTE). and we implement an analytical model of X-ray…
