Dynamical investigation of the multiple star ADS 9173 AB

Autor: Kiyaeva, O. V., Izmailov, I. S., Narizhnaya, N. V., Romanenko, L. G.

Star ADS 9173=WDS 14135+5147=Hip 69483 is a complex system. The B component has a spectroscopic companion, whose orbit with a period of 4.9 years has been known since 1986. The Gaia telescope has detected a distant faint pair over 100 arcsec away fro

Report

The orbits of visual binary and multiple stars obtained by the Apparent Motion Parameters method during the last 40 years

Autor: Romanenko, L. G., Kiyaeva, O. V., Izmailov, I. S., Shakht, N. A., Gorshanov, D. L.

Publikováno v: Publications of the Pulkovo Observatory, 227, 2022, p.146-158

Summed many years of work at Pulkovo, the orbits of 67 wide pairs of visual double and multiple stars (included in 64 systems) which were obtained by the Apparent Motion Parameters (AMP) method are presented. This short arc determination orbit method

Does ADS 9346 have a low-mass companion?

Autor: Kiyaeva, O. V., Khovritchev, M. Yu., Kulikova, A. M., Narizhnaya, N. V., Vasilyeva, T. A., Apetyan, A. A.

Based on the photographic and the CCD observations of the relative motion of A, B components of the binary system ADS~9346 obtained with the 26-inch refractor of the Pulkovo Observatory during 1979-2019, we discover an invisible companion associated

Photocentric orbits from a direct combination of ground-based astrometry with Hipparcos II. Preliminary orbits for six astrometric binaries

Autor: Gontcharov, G. A., Kiyaeva, O. V.

Publikováno v: New Astronomy 15 (2010) 324-331

Based on a direct combination of the Hipparcos data with astrometric ground-based observational catalogues having epochs between 1938 and 1999 the preliminary orbits and component masses are calculated for 6 binaries with no previous orbit calculatio
