RXTE observations of X-ray transients IGRJ17091-3624 and IGRJ18539+072

Abstract

We present results of analysis of observations of two transient sources IGR J17091-3624 and IGR J18539+0727 in April 2003 with RXTE observatory. Obtained energy spectra of sources, and also power spectra of their flux variations give us a possibility to classify them as X-ray binary systems in low/hard spectral state. Parameters of power spectrum of IGR J18539+0727 indicates that this source is a black hole candidate.
