摘要 X射线卫星ROSAT观测得到的X射线源1RXP J160338+1554.1,经过美国基特峰国立天文台的4 m光学望远镜的分光观测得到了它的光谱.通过光谱分析发现,该源具有较强的低电离发射线,从发射线的强度比以及谱线形态来看,该源完全符合低电离核发射线区(LINERs)星系的判据.这是第一次完全证实它是一个LINER. The ROSAT X-ray source, 1RXP J160338+1554.1, was observed spectroscopically with the 4m telescope at KPNO. It is confirmed as a LINER by its relatively strong low-ionization emission lines, its diagnostic ratios of optical line intensities, and its morphology.
