An Analysis of Four Candidate Physical Double-Star Systems and A Possible Binary

Abstract

This investigation analyzes four separate double-star systems: WDS 09119-3814 WFC 80, WDS 07181+0421 STF 1063 BC, WDS 05193-1045 STF 688, and WDS 05036-2029 WHC 1. The position angle and separation values for each system were obtained by taking nine to ten images for each system using the Las Cumbres Observatory Global Telescope network's 0.35m telescopes. AstroImageJ measurements were plotted alongside position angle and separation measurements from the Washington Double Star Catalog and data from the European Space Agency’s Gaia DR3 to determine whether there is a trend. The resulting measurements were analyzed to determine the likelihood that the systems have physically related or gravitationally bound stars. For all four systems, the measured position angle and separation values were similar to previous measurements. Our investigation suggests that three of the four systems may be physically related and that WDS 07181+0421 STF 1063 BC may be gravitationally bound.
