The role of magnetic fields during the birth and death of stars

恒星的诞生和死亡的研究具有根本性的重要性。恒星和行星系统是在气体云坍塌的过程中通过复杂的物理过程形成的。在恒星生命的末期，流出是恒星、行星和生命形成所必需的重元素的主要来源。艾美奖诺太奖的主要应用之一：恒星演化过程中的磁性关于恒星的形成和最终演化的问题涉及磁场的作用。只有在不同空间尺度上的偏振观测才能测量恒星演化这些阶段的磁场强度和结构。由于处于这些演化阶段的恒星被尘埃包裹的高度遮挡，因此最好通过对亚毫米(0.3-1毫米)和射电(1-20厘米)波长的分子和尘埃的观测来探测它们。拟议的研究小组将使用最先进的亚毫米和无线电仪器来研究磁场在恒星形成和演化恒星流出过程中的作用和来源。这些观测将揭示磁性在调节原恒星盘和流出的产生，以及在驱动和塑造演化恒星的质量损失方面的重要性。

The study of the birth and death of stars is of fundamental importance. Stars and planetary systems are formed through complex physical processes during the collapse of gas clouds. At the end of a stars life, outflows are the main source of heavy elements that are essential for the formation of stars, planets and life. One of the main Emmy Noether application: Magnetism during stellar evolution questions that remain about the formation and final evolution of stars concerns the role of magnetic fields. Only polarization observations at different spatial scales are able to measure the strength and structure of magnetic fields during these stages of stellar evolution. Because stars in these evolutionary phases are highly obscured by dusty envelopes, they are best probed through observations of molecules and dust at submillimeter (0.3-1 mm) and radio (1-20 cm) wavelengths. The proposed research group will use state of the art submillimeter and radio instruments to examine the role and origin of magnetic fields during star-formation and in the outflows from evolved stars. These observations will reveal the importance of magnetism in regulating the creation of protostellar disks and outflows, as well as in driving and shaping the mass-loss of evolved stars.
