Accretion Disk and Stellar Mass Transfer - Cosmic Phenomenon Explained #3062739 (License: Personal Use)

This illustration depicts mass transfer from a donor star (left) via an accretion stream into a bright, turbulent blue accretion disk surrounding a central compact object-possibly a black hole or neutron star. The intense gravitational pull heats the infalling gas, causing it to emit strongly in X-ray and ultraviolet wavelengths. Spiral structures and shock fronts within the disk indicate angular momentum transport and viscous heating.

Used in astronomy education, science news articles, and astrophysics outreach to explain binary systems, accretion physics, and high-energy phenomena. Matches user intent for visual understanding of stellar evolution, compact objects, and cosmic energy release mechanisms.
