Astrometric Measurements and Investigation of 10 Double Star Systems within the framework of the PLS – Piano Lauree Scientifiche 2024

Abstract

This study presents the astrometric measurements and investigations of 10 visual double star systems: WDS 11329+5525, WDS 06303+3027, WDS 10181+2731, WDS 10216+4609, WDS 10402+3824, WDS 10285+4733, WDS 06391+5503, WDS 09142+2518, WDS 09082+2353 and WDS 10453+4458. Conducted by high school students in collaboration with university tutors within the framework of the PLS – Piano Lauree Scientifiche Astrophysics course for the 2023-2024 academic year, the research aimed to enhance the understanding of stellar dynamics and the classification of binary systems. Utilizing advanced imaging techniques and software tools such as AstroImageJ, the students measured the position angles (θ) and angular separations (ρ) of the star pairs, contributing to the historical data on these systems. The measurements were compared with historical records from the Washington Double Star Catalog and GAIA data to assess the physical relationships between the components. The results indicate varying degrees of common proper motion and potential gravitational binding among the pairs, providing insights into their evolutionary paths. This collaborative project not only fostered a deeper appreciation for observational astronomy among the students but also contributed valuable data to the ongoing study of double star systems, highlighting the importance of educational initiatives in advancing astronomical research.
