Circumstellar dust : ウィキペディア英語版 | Circumstellar dust
Circumstellar dust is astronomical dust around a star. It can be in the form of a spherical shell or a disc, 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. The motion of circumstellar dust is governed by forces due to stellar gravity and radiation pressure. Circumstellar dust in our own Solar System causes the zodiacal light.
