Roche Lobe Overflow occurs in binary star systems when one star expands beyond its Roche lobe, leading to the transfer of mass to its companion star. This process can significantly alter the evolution and characteristics of both stars, often resulting in phenomena such as accretion disks and X-ray emissions.

Binary star systems consist of two stars orbiting a common center of mass, and they are crucial for understanding stellar masses and evolution. Observations of these systems can provide valuable insights into gravitational interactions and the life cycles of stars.

Mass transfer is the movement of mass from one location to another, often occurring in processes such as diffusion, convection, and phase change. It plays a critical role in engineering applications like chemical reactors, environmental systems, and separation processes, where the efficient transfer of mass is essential for system performance and optimization.

Stellar characteristics

Accretion disks are rotating structures of gas, dust, and other material that form around massive celestial objects, such as black holes, neutron stars, or young stars, due to gravitational attraction. These disks play a crucial role in the growth of the central object and emit significant electromagnetic radiation, often observed in X-ray and visible wavelengths, as material spirals inward and heats up due to friction and other processes.

X-ray emissions are a form of electromagnetic radiation with wavelengths shorter than ultraviolet light, often produced by high-energy processes such as those in astronomical phenomena or medical imaging. Understanding these emissions is crucial for applications ranging from diagnosing medical conditions to studying cosmic events like black holes and supernovae.
