Astroinformatics: The Importance of Mining Astronomical Data in Binary Stars Catalogues
Abushattal, A. A.; Alrawashdeh, A. A.; Kraishan, A. F.
The field of Astroinformatics offers exciting new perspectives on astronomical discovery through the implementation of advanced data mining procedures. Data deluges transform research practices and methodologies across various scientific disciplines, including day-to-day astronomical research. It is essential to use innovative algorithms and metho…
New late-type stars found in the BAO Plate Archive
Kostandyan, G. R.; Abrahamyan, H. V.; Paronyan, G. M. +1 more
The BAO Plate Archive low-resolution spectral plate centered \alpha = +04h; \delta = +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 …
Semi-detached double-lined eclipsing binaries with Gaia DR3 data
Malkov, O. Yu.; Grinenko, A. D.; Sachkov, A. M.
Semi-detached double-lined eclipsing binaries (SD DLEB) play an important role in our understanding of basic properties of interacting binaries. We have collected data on semi-detached systems with available light and radial velocity curve solutions, and have compiled the most comprehensive list of SD DLEB, containing astrophysical and orbital par…
First Byurakan Spectral Survey. Late-Type Stars. Dwarfs
Gigoyan, K. K.; Gigoyan, K. S.; Kostandyan, G. R. +5 more
A total of 18 lists of the First Byurakan Survey of Late-Type Stars (FBS LTS) were published between 1990 and 2016. The stars were found on FBS low-dispersion spectral plates. A systematic search and selection were carried out on a surface of ∼16 000 deg^2 on almost the whole area of the FBS. Since 2007, all FBS low-resolution spectral plates have…
The Precise Individual Masses and Theoretical Stability and Habitability of some Single-lined Spectroscopic Binaries
Abushattal, A. A.; Kraishan, A. F.; Algnamat, B. S. +1 more
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 mas…
Gaia EDR3 Data For Three Young Stellar Objects
Gigoyan, K. K.; Gigoyan, K. S.; Azatyan, N. M.
We present Gaia Early Data Release 3 (GaiaEDR3) high accurate astrometric and photometric data and also Catalina Sky Survey (CSS) phase-dependent light curves for three Young Stellar Objects (YSO). They are LRL245, 2MASSJ04300424+3533238, and CVSO592. These tree YSOs are presented as periodic variables in the Catalina Surveys Data Release-1 (CSDR1…
