Abstract:

With the advent of large astronomical surveys, the need of identification of the most interesting astrophysical object is required. In this work we focus on extracting red giant metal-poor stars from the LAMOST DR5. We then query the 5-D space coordinates from the Gaia DR2 to investigate their energy-action space. This sample will be used for studying the chemical and dynamical evolution of the early galactic phase. Also, identifying stars with kinematical similarities would enable us to trace the galactic assembly.

General note:

Communications of the Byurakan Astrophysical Observatory (ComBAO) is a peer-reviewed scientific journal, which publishes research in observational and theoretical astronomy/astrophysics and presents recent advances in these fields. It is being published by the NAS RA V. Ambartsumian Byurakan Astrophysical Observatory (BAO) in English in electronic form. The journal publishes original papers, review papers, brief reports, book reviews, special communications, observational and theoretical results in various fields of astronomy and related sciences, and some editorial notes, including anniversaries and obituaries. Under the heading “Legacy”, the renewed magazine will republish some old articles of high value in English. The heading “Guest articles” will bring to the attention of readers the articles of researchers who are not employees of BAO. ComBAO was founded in 1946 and regularly published in 1946-1990. However, the publication was interrupted because of the economic situation after the disintegration of the Soviet Union in 1991.
