Theoretical Studies of Magnetic Degenerate Stars

众所周知，许多恒星物体都具有磁场。在一些恒星中，比如太阳，磁场相对较弱，主要集中在某些区域。在其他恒星中，例如一些白矮星或中子星，磁场可能非常强，比地球磁场强一百万倍甚至更多。首席研究员建议研究激变双星系统(通常包含一颗白矮星)和中子星中的磁场。特别是，他将研究从这些恒星的磁场区域发出的辐射，即回旋辐射。当快速运动的带电粒子进入磁场并经历旋转加速时，辐射就会产生。PI预计，对激变双星的回旋辐射的研究将提高我们对这些系统中恒星成员之间质量交换的理解。对中子星回旋辐射的研究应该提供有关观测到的这些天体自转减速和加速的信息。

Many stellar objects are known to possess magnetic fields. In some stars, as in the case of the sun, the magnetic fields are relatively weak and chiefly concentrated in certain regions. In other stars, such as some of the white dwarfs or neutron stars, the magnetic fields may be very strong, exceeding the terrestrial magnetic field by factors of a million and more. The Principal Investigator proposes to investigate the magnetic fields found in cataclysmic binary star systems (which typically contain a white dwarf) and in neutron stars. In particular, he will study the emission of radiation, known as cyclotron emission, from the magnetic field regions of these stars. The emission arises when fast moving charged particles enter the magnetic fields and experience rotational accelerations. The PI expects that the investigation of cyclotron emission from cataclysmic binaries will improve our understanding of mass exchange between the stellar members of these systems. The investigation of cyclotron emission from neutron stars should provide information about the observed slowing down and spinning up of the rotation of these objects.
