Circumstellar envelope
From Wikipedia, the free encyclopedia
Circumstellar envelope is the part of the star, having roughly spherical shape and not gravitationally bound to the star core. Usually circumstellar envelopes are formed from the dense stellar wind or present before formation of the star. Circumstellar envelopes of the old stars [1] are eventually evolving into Protoplanetary nebulae, and circumstellar envelopes of the young stellar objects [2] are evolving into Circumstellar discs.
