- Circumstellar Dust is astronomical dust around a star. It can be in the form of a spherical shell or a disk, e.g. an accretion disk. Circumstellar dust can be responsible for significant extinction and is usually the source of an infrared excess for stars that have it.
- 星周塵是環繞在恆星周圍的塵埃,它可以是球殼或是盤狀,也就是吸積盤。星周塵對恆星的消光負有很大的責任,同時也是造成恆星紅外超的主要源頭。
