项目摘要

This project will combine near infrared spectroscopy and radio continuum imaging. The spectroscopy allows the study of the molecular absorption lines, which give the structure of the cool gas very near to the star, and hydrogen and helium emission lines, which gives the velocity structure of any jet or wind present. These will be compared with the expected results from existing models for young protostars of this mass. Radio continuum data will also be used to study the jets. Continuum radio data will quantify the mass loss rate from the star. The high spatial resolution offered by radio imaging will be used to study the evolution, further constraining the emission mechanism present.This project will combine near infrared spectroscopy and radio continuum imaging.

该项目将联合收割机近红外光谱和无线电连续成像相结合。光谱学允许研究分子吸收线，这给出了非常接近星星的冷气体的结构，以及氢和氦的发射线，这给出了任何喷流或风的速度结构。这些将与现有模型的预期结果进行比较，年轻的原恒星的质量。无线电连续数据也将用于研究喷流。连续谱无线电数据将量化星星的质量损失率。无线电成像提供的高空间分辨率将用于研究演化，进一步限制目前的发射机制。该项目将结合联合收割机近红外光谱和无线电连续成像。光谱学允许研究分子吸收线，这给出了非常接近星星的冷气体的结构，以及氢和氦的发射线，这给出了任何喷流或风的速度结构。这些将与现有模型的预期结果进行比较，年轻的原恒星的质量。无线电连续数据也将用于研究喷流。连续谱无线电数据将量化星星的质量损失率。无线电成像提供的高空间分辨率将用于研究演变，进一步限制目前的发射机制。
