The evolution of these binary systems, from their initial formation to eventual mergers, produces observable gravitational waves. Understanding this evolution relies heavily on understanding the properties of the stars within these systems, and these properties can be deduced from the observed orbital motions.
Binary systems offer distinct advantages over isolated neutron stars. The presence of a companion star can significantly influence a neutron star's properties, affecting its mass, spin, and orbital parameters. Observation of these parameters, especially in the case of binary neutron stars, is critical for testing models of neutron star interiors and the theory of general relativity. Analysis of binary systems involving neutron stars allows for a more nuanced understanding of stellar evolution compared to examining isolated neutron stars, as the interactions within binary systems can accelerate certain evolutionary processes, for instance, the development of gravitational instability leading to merging events. Real-world examples include the observed mergers of binary neutron stars, events that have been detected by gravitational wave observatories. These detections, precisely timed and aligned with theoretical models, provide strong evidence supporting models of binary star evolution and neutron star properties.
