An algorithm to calculate the relative orbit, ephemeris, and individual masses of unresolved astrometric binaries. Example of application on the newest Gaia DR3 binaries: the ESMORGA catalog
Xabier Pérez-Couto, Jose Á. Docobo, Pedro P. Campo
The recent Gaia Data Release 3 has unveiled a catalog of over eight hundred thousand binary systems, providing orbital solutions for half of them. Since most of them are unresolved…
Physical and Dynamical Parameters of the Triple Stellar System: HIP 109951
Suhail Masda, J. A. Docobo, A. Hussein +5
The precise determination of the physical and dynamical parameters of the HIP 109951 triple star system (WDS J22161-0705AB) which is formed by the A, Ba, and Bb components are pres…
Physical and Geometrical Parameters of CVBS XII: Fin 350 (Hip 64838)
M. A. Al-Wardat, J. A. Docobo, A. A. Abushattal +1
A complete astrophysical and dynamical study of the close visual binary system (CVBS) (A7V + F0V), Finsen 350, is presented. Beginning with the entire observational spectral energy…
Precise orbital elements, masses and parallax of the spectroscopic-interferometric binary HD 26441
Jose A. Docobo, Roger F. Griffin, Pedro P. Campo +1
The orbit of the visual-speckle binary A 2801 (HD 26441) was calculated independently of the previously published double-lined spectroscopic solution, obtaining similar values for…
Improved orbits and parallaxes for eight visual binaries with unrealistic previous masses using the Hipparcos parallax
J. A. Docobo, V. S. Tamazian, O. Yu. Malkov +2
Improved orbits are presented for the visual binaries WDS 02366+1227, WDS 02434-6643, WDS 03244-1539, WDS 08507+1800, WDS 09128-6055, WDS 11532-1540, WDS 17375+2419, and WDS 22408-…
New distances for a selected set of visual binaries with inconsistent dynamical masses
V. S. Tamazian, O. Y. Malkov, J. A. Docobo +2
We have selected a set of 17 visual binaries that demonstrate great inconsistency between the systemic mass obtained through Kepler's Third Law as compared to that calculated throu…
