The title speaks for itself. I'm just curious and I couldn't find anything on it. Particularly, what if they are a close binary (period less than 50 days)?

Yes, it is possible for binary stars to have the same radius but different masses. This is because the radius of a star is determined by its mass, temperature, and luminosity. Therefore, two stars with different masses but the same temperature and luminosity can have the same radius.
Binary stars are formed when a cloud of gas and dust collapses due to gravity, forming two or more protostars. These protostars then continue to accrete material and eventually become fully formed stars, orbiting each other due to their mutual gravitational attraction.
Yes, binary stars can have different ages. This is because they can form from different parts of the same gas cloud, which may have different densities and compositions. Additionally, one star may evolve faster than the other, leading to a difference in their ages.
Binary stars with the same radius but different masses can provide valuable information about stellar evolution and the physical processes that govern it. By studying these stars, we can better understand how a star's mass affects its structure, lifespan, and eventual fate.
Yes, binary stars with the same radius but different masses can coexist peacefully. As long as the stars are in stable orbits and do not come too close to each other, their different masses should not cause any disturbances. However, if one star is significantly more massive, it may have a stronger gravitational influence on the other star, potentially leading to interactions or even mergers.
