We are pleased to welcome Yongquan Xue, a professor at the Department of Astronomy, University of Science and Technology of China (USTC), as a guest blogger. He is an astrophysicist whose main research field is X-ray high-energy astrophysics, and has been significantly involved in the Chandra Deep Fields. Yongquan led the Nature paper that is the subject of our latest press release on the discovery of a magnetar-powered X-ray transient. Before joining USTC in 2012, he worked at Penn State University as a postdoc, after obtaining his astrophysics B.S. and M.S. degrees at Peking University, and Ph.D. degree at Purdue University, respectively.
A neutron star is the compact object formed after a supernova explosion occurring in the late evolutionary stage of a massive star, and it is one of the most mysterious objects in the universe. It is composed of almost all neutrons, and has some extreme physical properties such as ultra-high density and a super-strong magnetic field. It is an excellent natural laboratory for testing basic physical laws. However, up to now, our understanding about the basic properties of neutron stars (e.g., the equation of state, which describes the relation among pressure, density, etc.) is still relatively vague.
