Understanding the Physics of Pulsar Core Radiation and Supernova "Kicks"

城市大小的，快速旋转的，被称为中子星的中子星主要通过它们的射频发射光束向天文学家展示，这些光束像灯塔信标一样扫过地球。这些无线电“闪光”列车表现出丰富多样的现象，反映了脉冲星磁层的复杂过程，反过来又反映了恒星表面以上的奇异物理条件。因此，脉冲星提供了独特的重要机会，以扩展和测试我们对极端条件下物理学的基本理解。在这里，脉冲星发射机制的研究将集中在两个密切相关的问题：他们的主要核心发射在单脉冲将首次调查;并且它的正交极化模式相对于磁场的方向将被确定，从而提供重要的新机会来评估，建模和发展适当的物理理论。分析和理论工作将由一个熟练和经验丰富的国际团队进行，该团队将包括兰金博士、研究生、本科生以及印度和欧洲的合作者。兰金博士还将继续向K-12学校和公众公开演讲。

The city-sized, rapidly rotating, neutron stars known as pulsars are revealed to astronomers primarily through their radio-frequency emission beams, which sweep past the Earth much like lighthouse beacons. These trains of radio "flashes" exhibit a rich variety of phenomena, reflecting complex processes in the pulsar magnetosphere that in turn reflect exotic physical conditions above the stellar surface. Pulsars thus provide uniquely important opportunities to extend and test our basic understanding of physics in extreme conditions. Here, the mechanism of pulsar emission will be studied by focusing on two closely connected issues: their predominant core emission in single pulses will be investigated for the first time; and the orientation of its orthogonally polarized modes relative to the magnetic field will be determined, thereby providing important new opportunities to assess, model, and develop appropriate physical theories.The observational, analytical and theoretical work will be conducted by a skilled and experienced international team which will include Dr. Rankin, a graduate student, undergraduates, and collaborators in India and Europe. Dr. Rankin will also continue her public talks on pulsars to K-12 schools and the general public.
