One of the most interesting observational discoveries in astronomy during the past decade is that of newly formed or newly forming stars in the dark, cold, and dense clouds of gas and dust in our and in other galaxies. These so-called young stellar objects (YSOs) display a variety of morphologies, including circumstellar disks, jets, diffuse patches of dust, and conical nebulae. The Principal Investigator proposes to study YSOs and to answer some of the outstanding questions relating to them, such as the physical conditions of the YSOs, the heating mechanism of the disks, and the origin of the jets.

在过去的十年里，天文学中最有趣的观测发现之一是在我们和其他星系中黑暗、寒冷、稠密的气体云和尘埃云中新形成或新形成的恒星。这些所谓的年轻恒星物体（yso）表现出各种各样的形态，包括星周圆盘、喷流、漫射尘埃斑块和锥形星云。首席研究员建议研究YSOs，并回答一些与之相关的悬而未决的问题，如YSOs的物理条件、圆盘的加热机制和射流的起源。
