Wide Binary Star Analysis with Gaia Data
Analysis
This paper leverages the extensive Gaia DR3 data to analyze the properties of wide binary stars. It introduces a new observable, projected orbital momentum, and uses it to refine mass distribution models. The study investigates the potential for Modified Newtonian Dynamics (MOND) effects and explores the relationship between binary separation, mass, and age. The use of a large dataset and the exploration of MOND make this a significant contribution to understanding binary star systems.
