Astrometric Measurement of 06337-7538 LDS169 with Analysis using GAIA DR3 and Orbital Modelling with Speckle ToolBox. Confirmation of a Binary System.

Abstract

06337-7538 LDS169 has a Grade 5 orbit in the Sixth Catalog of Orbits of Visual Binary Stars. The nature of 06337-7538 LDS169 was further investigated using a current measure, GAIA DR3 data and Speckle ToolBox. 06337-7538 LDS169 was imaged using the Las Cumbres Observatory (LCO) network of telescopes. Calibrated images were obtained and analysed using the software AstroimageJ to determine separation, position angle and delta magnitude. Using the GAIA DR3 data and apparent separation reported in this paper, physical distance separation was estimated. In addition, the Harshaw rating and Buccheim distance probability estimation were calculated. 06337-7538 LDS169 has an E_binding value <0. Minor changes occurred in the orbital parameters following optimization using the orbits function of Speckle ToolBox. The analysis of 06337-7538 LDS169 confirms that it is a binary star system.
