Launching and Collimation of Outflows from Young Solar-type Stars

Pi和她的团队将应用2D和3D磁流体力学模拟来观测到年轻太阳型恒星的准直流出。他们将遵循两个阶段的方法：1)在小于1AU的小空间尺度上调查发射和准直，然后将工作扩展到10-100AU的更大尺度的模拟。第二阶段的模拟将与在类似距离尺度上流出的年轻恒星对象(YSO)的观测结果进行比较。该项目还将对其他与恒星天体物理相关的主题做出贡献，包括发展对经历引力坠落的物质的物理理解和直觉，约束初始质量函数和角动量的模型。国际和平研究所将指导一名博士后研究人员和本科生参与这一研究项目，并将通过伊萨卡科学中心组织和开展一次公众宣传活动。

The PI and her team will apply 2D and 3D magnetohydrodynamic simulations to observed collimated outflows from young solar-type stars. They will follow a two phase approach of 1) investigating launching and collimation on small spatial scales of less than 1 AU, and then 2) extending the work to simulations of much larger scales of 10-100 AU. Simulations from the second phase will be compared to observations of young stellar objects (YSO's) with outflows over similar distance scales. The project will also contribute to other topics relevant to stellar astrophysics, including developing physical understanding and intuition about material undergoing gravitational infall, constraining models of initial mass functions and angular momentum. The PI will mentor a postdoctoral researcher and undergraduate students in participating in this resarch project, and will also organize and run a public outreach exibit through the Ithaca Science Center.
