Abstract:
The paper presents orbits of 69 wide pairs of visual binary and
multiple stars (part of 65 systems) obtained by the Apparent Motion
parameters (AMP) method. Problem statement: The possibility of
determining the AMPorbits of these pairs using Gaia DR3 data at the
moment 2016.0 is considered. Results: 1) Orbits according to Gaia DR3
were obtained for 45 pairs. 2) For another 20 pairs, the
quasi-instantaneous motion according to Gaia data contradicts the
average motion from all available observations. A possible reason is
the presence of internal subsystems. 3) We also give AMP orbits for 3
bright stars (ADS 2080, ADS 7724, and ADS 9173) and 3 close pairs
(less than 2": ADS 2416, ADS 5570, and T Tau NS) that do not have the
Gaia DR3 positional observations. The basis for the study in cases 2
and 3 are the Pulkovo series of observations on the 26-inch refractor
and/or data from the literature. Of the 69 pairs of stars studied, 59
have a semi-major axis of the orbit greater than 100AU. Among them,
for 17 pairs, families of orbits with minimum periods from 5 thousand
to 730 thousand years and minimum semi-major axes of more than 400AU
were obtained. The only possible solutions were obtained for the
orbits of 28 pairs. Of these, 20 pairs have a semi-major axis of the
orbit greater than 100AU and periods from 600 to 6000 years. Relative
errors in determining the elements are generally about 15-20%. The
orientation of the resulting orbits in the galactic coordinate system
is also determined.
Description:
Table1 provides common data about the stars: number one after another,
Hipparcos number, ADS number, components, WDS number (coordinates);
magnitudes and spectral classes of components according to WDS; masses
of components according to MSC (2024 version) and from the Gaia DR3
catalog; time interval and number of observations in WDS (2016
version), time interval and number of photographic and CCD
observations with the Pulkovo 26-inch refractor, number of solutions,
any flags and references.
Table2 presents the apparent (relative) motion parameters and
additional parameters as initial data for AMP orbit determinations.
Table3 gives the AMP orbits and their uncertainties for 52 pairs with
1, 2 or 4 solutions, comparison with observations (RMS). And also we
give coordinates of the orbit Pole and Periastron directions in the
Galaxy reference frame. Orbital element uncertainties are determined
by the total effect of initial data errors, but they are asymmetrical
with respect to the calculated values of the orbital elements,
therefore we give two values of uncertainties: positive and negative.
In the table4 - The Families of AMP orbits for 17 pairs corresponding
to special solutions, their comparison with observations and also we
give coordinates of orbital Pole and Periastron directions in the
Galactic reference frame.
Table5 (table_A) is a sampling of Gaia DR3 data necessary for applying
the AMP method to the Catalog's objects. There are positions, proper
motions, parallaxes, radial velocities and masses for each components
of Pulkovo program stars. Table5 also gives their identifications
(ADS, WDS and HIP number), effective temperature and parameter RUWE,
if were available.
