给出了年轻星体的近红外图像(1-2.2微米)，其中光分布是由星周尘埃对中心星体辐射的扩散和吸收造成的。物质的分布被模拟为圆盘、团块和被风吹起的空穴的组合。探索了圆盘的各种密度规律，并用数值实验检验了模型的三个组成部分在整体图像中的各自作用。决定图像纵横比的基本因素是盘的中心冷凝程度。参考文献29。
Near-infrared images (1-2.2 microns) of young stellar objects, where the light distribution results from diffusion and absorption of radiation of the central stellar object by circumstellar dust, are presented. The distribution of matter is modeled as a combination of a disk, a clump, and a wind-blown cavity. Various density laws for the disk are explored, and numerical experiments are used to test the respective role of the three constituents of the model in the overall image. The essential factor that determines the aspect of the image is the degree of central condensation of the disk. 29 refs.
