An Astrometric Measurement of 01589-5652 LDS63 and Analysis using GAIA DR3 Data

Abstract

The components of WDS 01589-5652 LDS63 show common proper motion and are included in the Luyten double star catalog. The nature of 01589-5652 LDS63 was further investigated using a current astrometric measure and GAIA DR3 data. WDS 01589-5652 LDS63 was imaged using the Las Cumbres Observatory (LCO) Global Network of Telescopes. Calibrated images were obtained and analysed using the software AstroImageJ to determine separation, position angle and delta magnitude. Using GAIA DR3 data and apparent separation reported in this paper, physical distance separation was estimated as well as the transverse space distance (without the radial component). In addition, the relative proper motion (rPM) metric, angle between each of the components space velocity vectors in 3-dimensional space, Buchheim distance probability estimation, binding energy (E_binding), system escape velocity and relative 3-dimensional space velocity were calculated. Analysis shows that the components of WDS 01589-5652 LDS63 have a physical and gravitational association indicating a binary star system.
