Binary Star System with Mass Transfer and Accretion Disk #3567530 (License: Personal Use)

This illustration shows a close binary system where a bloated red giant star loses mass through Roche-lobe overflow, feeding a hot, luminous accretion disk around a compact object-likely a black hole or neutron star. The disk emits intense radiation, and powerful relativistic jets erupt perpendicularly from the poles, characteristic of active accretion systems. Such configurations are key to understanding X-ray binaries, gamma-ray bursts, and gravitational wave progenitors.

Used in astrophysics education, science journalism, and astronomy outreach to visualize mass-transfer binaries, accretion physics, and high-energy astrophysical processes; targets users seeking explanations of stellar evolution, compact objects, or exotic cosmic events.
