最近类星体对候选者的重新分类：SDSS J15244 +3032 - RXS J15244 +3032
Reclassification of the nearest quasar pair candidate: SDSS J15244+3032 - RXS J15244+3032
摘要：
我们给出了第13版Veron-Cetty & Veron星表中最近的类星体对，即SDSS J15244+3032和RXS J15244+3032（红移z~0.27，角距~7 arcsec，视线速度差~1900 km/s）的光谱学结果。该系统将是一个最佳的候选人，研究与地基光学成像和光谱的宿主星系的相互作用。然而，新的光学数据表明RXS J15244+3032确实是一颗光谱类型为G的恒星。本文包括Asiago 1.82米望远镜（Cima Ekar天文台，Asiago，意大利）收集的数据。
英文摘要：
We present optical spectroscopy of the nearest quasar pair listed in the 13th edition of the Veron-Cetty & Veron catalogue, i.e. the two quasars SDSS J15244+3032 and RXS J15244+3032 (redshift z~0.27, angular separation ~7 arcsec, and line-of-sight velocity difference ~1900 km/s). This system would be an optimal candidate to investigate the mutual interaction of the host galaxies with ground based optical imaging and spectroscopy. However, new optical data demonstrate that RXS J15244+3032 is indeed a star of spectral type G. This paper includes data gathered with the Asiago 1.82m telescope (Cima Ekar Observatory, Asiago, Italy).
