Observations of the Black Hole candidate GX339-4 with the TTM telescope of the "KVANT" module on board the "MIR" orbital station
Abstract
TTM device of the "KVANT" module onboard the "MIR" russian space station had obtained two series observations of the X-ray source Black Hole candidate GX339-4 in 1989-1994. Soft state of source, in wich source spectrum (2-28 keV) was approximated by the multi-color accretion disk model with absorption, has been founded in March 1989. Hard state of source with spectrum approximated by the power law with absorption and transfer from the hard to the soft state has been observed in the March 1994. Various source spectrum states are the prove of its belonging to the Black Hole candidates class.
