摘要
Herbig Ae/Be (HAeBe) stars, young stars surrounded by dust shells, are believed to be precursors of β Pic-like stars, and the dust around them is thought to be a possible source material for the formation of planets. A group of the HAeBe stars (UX Ori, WW Vul, etc.) shows large brightness variations. The dust in the vicinity of these stars is responsible not only for their excess emission in the infrared, anomalous extinction in the ultraviolet and visual, and specific spatial distributions of the intensity and polarization, but also for the “blueing” effect in the colour-magnitude diagrams and the intrinsic polarization increase observed in deep minima.
