摘要
The source XTE J1901+014 discovered by the RXTE observatory during an intense outburst of hard radiation and classified is 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 (similar to 0.5-1 Crab) outbursts more than several hundred seconds in duration. Certain assumptions about the nature of the object under study are made.
