Relating to or located around a star; orbiting or surrounding a star.
From Latin circum- 'around' + stella 'star.' The term was coined in astronomy to describe objects or regions in the vicinity of stars. Modern usage particularly describes stellar disks and debris.
Circumstellar disks are the dusty rings of material around stars where planets can form—astronomers use this term constantly when discussing how solar systems are born. You might find circumstellar dust around Vega or Sirius.
