mass loss

Definition

Astronomy

  • Removal of material from stars, especially from heavy stars which can shrink from 50 to 3 solar masses during supernova explosions, with a dramatic effect on their later evolution. The mass loss leaves them below the mass required to collapse into a black hole. On a less dramatic scale, mass is lost to stars when companions nearby suck it away, especially in contact binary stars where the stars are close together.
