INTEGRAL observations of Her X-1
D. Klochkov, R. Staubert, K. Postnov +6
Aims: We investigate the X-ray spectral and timing properties of the accreting X-ray pulsar Her X-1 observed with the INTEGRAL satellite in July-August 2005. Methods: The data anal…
The pre-outburst flare of the A 0535+26 August/September 2005 outburst
I. Caballero, A. Santangelo, P. Kretschmar +11
We study the spectral and temporal behavior of the High Mass X-ray Binary A 0535+26 during a `pre-outburst flare' which took place ~5 d before the peak of a normal (type I) outburs…
INTEGRAL observations of HER X-1
D. Klochkov, R. Staubert, S. Tsygankov +7
First results of observations of the low mass X-ray binary Her X-1/HZ Her performed by the INTEGRAL satellite in July-August 2005 are presented. A significant part of one 35 day ma…
Long-term developments in Her X-1: Correlation between the histories of the 35 day turn-on cycle and the 1.24 sec pulse period
R. Staubert, S. Schandl, D. Klochkov +3
We have studied the long-term (1971-2005) behaviour of the 1.24 sec pulse period and the 35 day precession period of Her X-1 and show that both periods vary in a highly correlated…
INTEGRAL Observations of SS433: Analysis of Precessional and Orbital X-ray Periodicities
A. M. Cherepashchuk, R. A. Sunyaev, E. V. Seifina +7
Hard X-ray INT observations of SS 433 carried out during 2003-2005 years with an analysis of precessional and orbital variability is presented. The width of X-ray eclipse in the 25…
Diagnostics of the black hole candidate SS433 with the RXTE
E. Filippova, M. Revnivtsev, S. Fabrika +2
We present our analysis of the extensive monitoring of SS433 by the RXTE observatory collected over the period 1996-2005. The difference between energy spectra taken at different p…
Observational evidence for a changing tilt of the accretion disk with respect to the orbital plane in Her X-1 over its 35 day cycle
D. Klochkov, N. Shakura, K. Postnov +3
Analysis and interpretation of the Her X-1 X-ray light curve obtained with the ASM onbord RXTE over the period 1996 February to 2004 September is presented. We report that the feat…
INTEGRAL observations of SS433: Results of coordinated campaign
A. M. Cherepashchuk, R. A. Sunyaev, S. N. Fabrika +18
Results of simultaneous INTEGRAL and optical observations of galactic microquasar SS433 in May 2003 and INTEGRAL/RXTE observations in March 2004 are presented. Persistent precessio…
Gravitational Radiation during Thorne-Zytkow object formation
S. N. Nazin, K. A. Postnov
Calculation of gravitational radiation during binary inspiral leading to possible formation of a Thorne-Zytkow (TZ) object (a neutron star inside a supergiant core) is performed. T…
