Stellar debris refers to the remnants of stars or other celestial bodies that have been destroyed or disrupted by gravitational forces, such as black holes or neutron stars. This debris can include particles, gas, and dust that are scattered throughout space. Studying stellar debris can provide valuable insights into the processes of stellar evolution, galaxy formation, and the dynamics of gravitationally bound systems. Scientists use a variety of tools, such as telescopes and computer simulations, to observe and analyze stellar debris and its effects on the surrounding environment.
