摘要:

We present the results of six Main‐On observations of Her X‐1, obtained by HEXE between 7/87 and 10/88 in hard x‐rays. Pulse period measurements confirm the long term spin‐up trend. A 16–60 keV pulse profile of excellent quality is given. The pulse‐minus‐off‐pulse spectrum is best represented by a power‐law with exponential cut‐off and a cyclotron absorption line (Ecycl=34.1±2.5 keV). ©1994 American Institute of Physics.
