The goal of this collaborative project is to explore the relationship between gas metallicity and star formation rate. It will use the VISTA Magellanic Clouds (VMC) near IR survey photometry to extend a catalog of young stellar objects (YSOs) to solar masses. The program will measure the amount of molecular gas present as a test of recent star formation theories and will ascertain the effects on the structure and formation of dense pre-stellar cores.Broader impacts of the work include training of undergraduate and graduate students and a postdoc in the use of ALMA, and release of GPIPS survey results and software to the astronomical community. The Baltimore-based postdoc and graduate students of Dr. Meixner will participate in Project ASTRO, which reaches out to the Baltimore City School system, while Co-I Dr. Indebetouw and his students will create new multi-wavelength components for K-12 teacher workshops.

这个合作项目的目标是探索气体金属丰度和星星形成率之间的关系。 它将使用VISTA麦哲伦云（VMC）近红外测量测光，将年轻恒星天体（YSO）目录扩展到太阳质量。该计划将测量存在的分子气体的量，作为对最近的星星形成理论的测试，并将确定对致密星前核结构和形成的影响。这项工作的更广泛影响包括培训本科生和研究生以及一名博士后使用阿尔马，并向天文界发布GPIPS调查结果和软件。Meixner博士在巴尔的摩的博士后和研究生将参加ASTRO项目，该项目涉及巴尔的摩城市学校系统，而Co-I Indebetouw博士和他的学生将为K-12教师研讨会创建新的多波长组件。
