摘要:

本文给出了在ESO/3.6米望远镜上拍摄的所谓高红移类星体Q 0045 -3337的中等分辨率光谱。我们的观测表明,该天体不是类星体,而是光谱类型为B的恒星。我们认为该天体是一颗白矮星或晕族蓝水平支星。

英文摘要:

We present a medium-resolution optical spectrum of the alleged high-redshift quasar Q0045-3337, taken at the ESO/3.6m telescope. Our observations show that the object is not a quasar but a star of spectral type B. We suggest that the object is either a white dwarf or a halo population Blue Horizontal Branch star.
