  • Identifying Li-rich giants from low-resolution spectroscopic survey 
    Bharat Kumar, Y; Reddy, B. E; Zhao, G (Indian Academy of Sciences, 2018-04)
    In this paper we discuss our choice of a large unbiased sample used for the survey of red giant branch stars for finding Li-rich K giants, and the method used for identifying Li-rich candidates using low-resolution spectra. ...
  • Interstellar extinction from photometric surveys: application to four high-latitude areas 
    Malkov, O; Karpov, S; Kilpio, E; Sichevsky, S; Chulkov, D; Dluzhnevskaya, O; Kovaleva, D; Kniazev, A; Mickaelian, A; Mironov, A; Murthy, J; Sytov, A; Zhao, G; Zhukov, A (De Gruyter, 2018-04)
    Information on interstellar extinction and dust properties may be obtained from modern large photometric surveys data. Virtual Observatory facilities allow users to make a fast and correct cross-identification of objects ...
  • Stellar and interstellar parameters from large photometric surveys 
    Malkov, O; Karpov, S; Kovaleva, D; Murthy, J; Sichevsky, S; Sytov, A; Zhao, G; Zhukov, A; Zakharo, A (NAS RA Byurakan Astrophysical Observatory, 2020-12)
    The parameterization of stars is a well known problem and used for various purposes in astronomy. We have shown that multicolor photometric data from large modern surveys can be used for parameterization of stars. With ...
  • Two New Super Li-rich Core He-burning Giants: A New Twist to the Long Tale of Li Enhancement in K Giants 
    Bharat Kumar, Y; Singh, R; Reddy, B. E; Zhao, G (IOP Publishing, 2018-05-10)
    In this Letter we report two new super Li-rich K giants, KIC2305930 and KIC12645107, with Li abundances exceeding that of the interstellar medium (ISM; A(Li) ≥ 3.2 dex). Importantly, both of the giants have been classified ...
