摘要

我们提出了GRO瞬态J0422+32的新光度观测结果，显示了2小时和5小时的振幅变化仅为0.1等。在1992年8月爆发后期和1993年8月爆发期间的光谱观测显示，双峰Balmer和He ii剖面在小时尺度上发生了变化，并揭示了两个时期的红移发射分量。

ING photometry and spectroscopy of the optical counterpart of the x‐ray transient GRO J0422+32

We present new photometric observations of the GRO transient J0422+32 which show a two‐hour and a five‐hour variation of only 0.1 magnitude in amplitude. Spectroscopic observations during the late decline of the August 1992 outburst and during the August 1993 outburst show variability in the double‐peaked Balmer and He ii profiles on a timescale of hours and reveal red‐shifted emission components at two epochs.
