To view the original source information, use the "Learn more" links.In a binary star system, the semi-major axis is the separation between the two stars. If the two stars have different masses, then each will orbit the center of mass with a different orbital radius. The semi-major axis a is just the sum of these two radii.spiff.rit.edu/classes/phys370/lectures/eclipse_1/ecli…In all binary systems both stars move in elliptical orbits about the centre-of-mass (COM). The semi-major axis is one-half the long axis of the ellipse. A circle is a special case of an ellipse with semi-major axis equal to the circle's radius.sites.ualberta.ca/~pogosyan/teaching/ASTRO_122/…What is the semi-major axis of binary stars? The semi-major axis of binary stars is the average distance between the two stars in a binary star system. It is the longest axis of the elliptical orbit that the stars follow around their common center of mass.www.physicsforums.com/threads/the-semi-major-a…Measuring the semi-major axis of a binary star system allows astronomers to determine the total mass of the system using Newton's laws. The semi-major axis remains constant for a given elliptical orbit, while the distance between the two objects varies as they move around the orbit.library.fiveable.me/key-terms/intro-astronomy/semi …
