Study of the fast X-ray transient XTE J1901+014 based on INTEGRAL, RXTE, and ROSAT data
The source XTE J1901+014 discovered by the RXTE observatory during an intense outburst of hard radiation and classified as a fast X-ray transient is studied. The source’s spectral characteristics in the quiescent state have been investigated for the first time both in the soft X-ray energy range (3 20 keV) based on ROSAT and RXTE data and in the hard energy range (>20 keV) based on INTEGRAL data. A timing analysis of the source’s properties has revealed weak nonperiodic bursts of activity on time scales of several tens of seconds and two intense (∼0.5 1 Crab) outbursts more than several hundred seconds in duration. Certain assumptions about the nature of the object under study are made.
