Small-scale circumstellar features around pre-main-sequence stars
Abstract
A number of very young stars show evidence of opacity changes with time apparently caused by circumstellar dust. It is demonstrated that these variations can be interpreted as evidence for infalling dust balls of cometary mass or larger. The total number of such balls around a given star may be inferred to be approximately 10 to the 12th.
