Astrometric Measurement and Analysis of Celestial Motion for Double Star WDS 10494+5517
Abstract
Our team observed and analyzed the double star system WDS 10494+5517 (HJ 2545) through the Las Cumbres Observatory (LCO) telescope network. We used the astrometric software SAOImage DS9 to measure new data for changes in mean position angle and mean separation distance. Our calculations revealed a new value of 25.9" ± 0.3" for the mean separation distance (rho) and a value of 114.2° ± 0.8° for mean separation angle (theta). Based on a consistent proper motion trend, very little retrograde motion or arcing, and a Harshaw value of 0.988, it is likely that HJ 2545 is an optical double.
