High Precision Radial Velocity Study of Young Stars

恒星形成于星际气体云和尘埃云中，这些气体云温度极低，呈块状，并且处于湍流状态。这种湍流以恒星运动的形式传递给新形成的恒星。首席研究员建议研究恒星形成区内新形成恒星的运动，使用大约800个高精度径向速度测量值作为数据库，测量了大约300个低质量主序前恒星。调查的目的是确定恒星的初始条件和早期演化。

Stars form in interstellar clouds of gas and dust that are extremely cool, clumpy, and in a general state of turbulence. This turbulence is passed on to newly formed stars in the form of stellar motions. The Principal Investigator proposes to study the motions of newly formed stars in star forming regions, using as a data base roughly 800 high-precision radial velocity measurements of some 300 low-mass pre-main sequence stars. The aim of the investigation is to determine the initial conditions and early evolution of stars.
