accretion processes

Accretion is the process where material, such as gas, dust, or other particles, gradually gathers and accumulates onto a larger object due to gravitational attraction. Over time, this builds up mass, forming larger bodies like stars, planets, or black holes. It often involves matter spiraling inward in a disk, releasing energy, and increasing the object's size and complexity. Accretion is fundamental in cosmic formation and evolution, shaping many celestial objects and systems in the universe.
