Over the past few decades, some Spectroscopic Binaries (SBs) have been resolved using high-resolution techniques. Astrophysics is interested in this subject because we can obtain the mass of each component. By combining a visual solution with a complimentary one, such as the spectroscopic orbit or Edward method, we can determine the individual masses, semimajor axes, magnitudes, spectral types, radii, and temperatures. These provide the most probable physical parameters for some single-lined spectroscopic binaries. Then We can use these parameters to calculate theoretical the stability and habitability of the system. Additionally, we assume the composite spectrum, the apparent global magnitude, and the parallax (generally the Hipparcos, and recently the Gaia ). The next step is to obtain the spectrum for each components. The Edwards method will be used in this case. As soon as we have two spectra foe two single-lined spectroscopic binaries (HIP 754 and HIP 3841), we can determine each mass based on the magnitude difference, Δm. For selected samples, we calculate the rest of the physical parameters needed to calculate the theoretical stability and habitability.

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.
