论文摘要
LISA（激光干涉仪空间天线）任务将在低频带中观察到0.1 MHz至1 Hz。在这个制度中，我们期望银河系二进制文件是重力波信号的主要（按数量）来源。考虑到银河系二进制物是由宇宙中磁性最大的天体物理物体组成的（即白矮人和中子星），丽莎有望带来有关退化星内磁性的起源和磁性的新信息。当前，数据处理假设银河系二进制系统是非磁性的，并且在圆形轨道上可能会偏向确定来源的参数以及检测器的校准。在这项工作中，我们研究了磁性对假设准圆形轨道的紧凑型银河系二进制发射的重力波的影响。
The LISA (Laser Interferometer Space Antenna) mission will observe in the low frequency band from 0.1 mHz to 1 Hz. In this regime, we expect the galactic binaries to be the dominant (by number) sources of gravitational waves signal. Considering that galactic binaries are composed of the most magnetized astrophysical objects in the universe (i.e., the white dwarfs and the neutron stars), LISA is expected to bring new informations about the origin and the nature of magnetism inside degenerated stars. Currently, the data processing assumes that the galactic binary systems are non-magnetic and in circular orbits which can potentially biased the determination of the parameters of the sources and also the calibration of the detector. In this work, we investigate the impact of magnetism on gravitational waves emitted by compact galactic binaries assuming quasi-circular orbits.
