摘要：
ROSAT performed the first, spectrally resolved, soft X-ray observations of Her X-1 in the SHORT-ON state of the 35(d) cycle. The data were taken during the All-Sky survey covering the range 0.1-2.4 keV. The mean luminosity in the ROSAT bandpass is 1.5 x 10(36)ergs sec(-1). Timing analysis of the data revealed a highly significant signal at a period of 1.237749(1) sec. Finally, we present evidence to support the hypothesis that the resuction in intensity during the SHORT-ON state is caused by hot matter absorption in the disk.
