The Digitized First Byurakan Survey (DFBS) is the digitized version of the First Byurakan Survey (FBS, or Markarian survey). The FBS was the first systematic survey of the extragalactic sky. This objective-prism survey was carried out in 1965-1980 by B.E.Markarian and his colleagues using the 1 m Schmidt telescope of the Byurakan Astrophysical Observatory and resulted in discovery of 1517 UVX-excess (Markarian) galaxies. FBS low-resolution spectral plates have been used for a long time to search and study faint Late-Type Stars (LTS, M-type and C stars) at high Galactic latitudes. A total of 18 lists of the FBS LTS were published between 1990 and 2016. We report newly confirmed C and M giants, and also large amount of M dwarfs based on the Gaia DR3 BP/RP low-resolution spectroscopic data base. Some of the newly confirmed M dwarfs presents binary systems. Some of them are new eclipsing binaries. In our previous studies of the DFBS spectral plates, all were presented as LTS candidates. Gaia high-accuracy astrometric and photometric data and Transiting Exoplanet Survey Satellite (TESS) data are used to characterize these new confirmed LTS. TESS phase-dependent light curves show rotational modulations and flares for many new M dwarfs. This confirmations of the large number of completely new objects represents a very significant extension in the census of M giants, faint N-type Asymptotic Giant Branch C stars, CH-type C giants at high Galactic latitudes, and M dwarfs in the solar vicinity. Some objects are located more than 7 kpc from the Galactic plane. Ultimately, we aim to present value-added catalog and update the FBS LTS catalog. Note that a large amount of the blue stellar objects with UVX-excess and numerous of emission line objects were also detected.

数字化首次 Byurakan 调查 (DFBS) 是首次 Byurakan 调查（FBS 或 Markarian 调查）的数字化版本。FBS 是对河外天空的第一次系统调查。这项客观棱镜巡天由 BEMarkarian 和他的同事于 1965 年至 1980 年使用 Byurakan 天体物理观测站的 1 m 施密特望远镜进行，结果发现了 1517 个 UVX 过量（Markarian）星系。FBS低分辨率光谱板长期以来一直被用来搜索和研究银河系高纬度地区微弱的晚型恒星（LTS、M型和C型恒星）。1990年至2016年间总共发布了18个FBS LTS列表。我们根据Gaia DR3 BP/RP低分辨率光谱数据库报告了新确认的C和M巨星，以及大量的M矮星。一些新确认的 M 型矮星呈现出双星系统。其中一些是新的食双星。在我们之前对 DFBS 光谱板的研究中，所有这些都被视为 LTS 候选者。盖亚高精度天体测量和光度数据以及凌日系外行星勘测卫星 (TESS) 数据用于表征这些新确认的 LTS。TESS 与相位相关的光变曲线显示了许多新 M 矮星的旋转调制和耀斑。对大量全新天体的确认代表了 M 巨星、微弱的 N 型渐近巨星分支 C 星、银河系高纬度的 CH 型 C 巨星和太阳附近的 M 矮星普查的非常重要的扩展。有些天体距离银河平面超过 7 kpc。最终，我们的目标是提供增值目录并更新 FBS LTS 目录。请注意，还检测到了大量 UVX 过量的蓝色恒星物体和大量发射线物体。
