摘要

通过对BAO Plate Archive低分辨率谱板的分析，发现了新的晚型恒星。已经发现了25颗新的晚型恒星。我们与GAIA DR3、USNO-B1.0、2MASS、AllWISE、IRAS PSC/FSC、AKARI和SDSS进行了相互关联。对于新探测到的天体，我们给出了由Gaia DR3和2MASS光度测量和可用的固有运动估计的光度等级。大多数天体都是红巨星。

New late-type stars found in the BAO Plate Archive

The BAO Plate Archive low-resolution spectral plate centered α = +04h δ = +240 is analyzed to find new late-type stars. 25 new late-type stars have been detected. We have performed cross-correlations with GAIA DR3, USNO-B1.0, 2MASS, AllWISE, IRAS PSC/FSC, AKARI and SDSS. For new detected objects, we present luminosity classes estimated from Gaia DR3 and 2MASS photometry and available proper motions. The majority of the objects are red giants.
