The last decade has shown us that the observational properties of neutron stars are remarkably diverse. From magnetars to rotating radio transients, from radio pulsars to isolated neutron stars, from central compact objects to millisecond pulsars, observational manifestations of neutron stars are surprisingly varied, with most properties totally unpredicted. The challenge is to establish an overarching physical theory of neutron stars and their birth properties that can explain this great diversity. Here I survey the disparate neutron stars classes, describe their properties, and highlight results made possible by the Chandra X-Ray Observatory, in celebration of its 10th anniversary. Finally, I describe the current status of efforts at physical "grand unification" of this wealth of observational phenomena, and comment on possibilities for Chandra's next decade in this field.
过去十年的研究表明,中子星的观测特性具有显著的多样性。从磁星到旋转无线电暂现源,从射电脉冲星到孤立中子星,从中子星形成的致密天体到毫秒脉冲星,中子星的观测表现出惊人的多样性,大多数特性都是完全无法预测的。挑战在于建立一个能够解释这种巨大多样性的关于中子星及其诞生特性的整体物理理论。在这里,我调查了不同的中子星类别,描述了它们的特性,并强调了钱德拉 X 射线观测站取得的成果,以庆祝其成立 10 周年。最后,我描述了在将这些丰富的观测现象进行物理“大统一”方面的努力的现状,并对钱德拉在该领域的下一个十年的可能性进行了评论。
