Link, Bennett"Crustal Dynamics in Neutron Stars"AST-0098728In astronomy, we commonly encounter physical conditions quite unfamiliar to us here on Earth. It gives us a chance to test physical theories which apply locally in order to see if they remain valid at extremes. Neutron stars represent one such extreme. Not only can we study properties of matter at almost incredibly high densities but also they are accompanied frequently by extremely strong and intense magnetic fields. Recent research has shown that neutron stars lead far from peaceful lives. Starquakes occur through cracking of the neutron star surface or crust and can cause large-scale realignments of the star's magnetic field. These may generate gamma-ray outbursts that can be detected by space observatories. During the course of this award four aspects of the effects of crust rigidity and their connection with spin behavior of the pulsar. Amongst other objectives, the work looks to determine the stage at which crust cracking begins and will provide estimates of the energy thereby released.***

Link，班尼特“中子星中的地壳动力学“AST-0098728在天文学中，我们通常会遇到地球上我们非常陌生的物理条件。 它给了我们一个机会来检验那些适用于局部的物理理论，看看它们在极端情况下是否仍然有效。 中子星就是这样一个极端。 我们不仅可以在几乎令人难以置信的高密度下研究物质的性质，而且它们经常伴随着极强和极强的磁场。 最近的研究表明，中子星的生活远非和平。 星震是通过中子星星表面或地壳的破裂而发生的，并可能导致星星磁场的大规模重新排列。 这些可能会产生伽马射线爆发，可以被空间观测站检测到。 在这个奖项的过程中，四个方面的地壳刚度的影响及其与脉冲星的自旋行为的联系。 除其他目标外，这项工作旨在确定地壳破裂开始的阶段，并将提供由此释放的能量的估计。
