WDS 03575-0110 Double-Star Astrometry

Astrometric analysis of a binary-star system using robotic telescope observations and historical measurements.

Joel conducted astrometric analysis of WDS 03575-0110 using robotic telescope observations from Las Cumbres Observatory. He used AstroImageJ to measure separation and position angle, compared new measurements with historical observations and Gaia DR3 data, evaluated common proper motion, and contributed to refining orbital parameter estimates.

Scientific question

How have the separation and position angle of WDS 03575-0110 changed over time, and what orbital parameters can be refined from combining new and historical measurements?
