标题： Gravitational radiation from highly magnetized nascent neutron stars in supernova remnants

摘要： 我们研究了超新星爆发后刚诞生的高磁化中子星，在超临界吸积流中的自旋演化问题。强磁场的存在可能会使恒星发生形变，如果磁场的对称轴与恒星旋转轴不重合，那么该恒星将成为引力波的发射源。在此，我们探讨当有物质以超临界流的形式落向这颗恒星时，它发出引力辐射的可能性。由于强烈的磁场作用，恒星的形状略微偏离球形；恒星的旋转角速度由吸积转矩和磁偶极辐射之间的平衡所决定。给出了此类系统引力辐射特征振幅的估算值。 （摘要简写） 显示英文摘要

摘要： We consider the spin evolution of highly magnetized neutron stars in a hypercritical inflow just after their birth in supernovae. Presence of a strong magnetic field could deform the star and if the symmetry axis of the field is misaligned with that of stellar rotation, the star will be an emitter of gravitational wave. Here we investigate the possibility of gravitational radiation from such a star when there is a hypercritical inflow onto it. The stellar configuration is slightly deformed away from spherical by the intense magnetic field; the rotational angular frequency of the star is determined by the balance between the accretion torque and the magnetic dipole radiation. An estimation of the characteristic amplitude of the gravitational radiation from such systems is given. (abridged abstract)
