标题： Gravitational pulsars: correlations between the electromagnetic and the continuous gravitational wave signal

摘要： 中子星发出连续引力波可以被视为引力脉冲星，从这个意义上说，有可能通过下一代引力波干涉仪的长基线观测来追踪其旋转周期的变化。 假设脉冲星的电磁信号被跟踪，并允许我们监测脉冲星的自转演化，我们提供了一种对可能观察到的这种定时解与其引力对应物之间相关性的物理解释，如果该系统也通过引力波被探测到的话。 特别是，我们表明，下一代探测器，如爱因斯坦望远镜，可能具有足够的灵敏度来区分中子星超流体和正常组分之间耦合的不同模型，并限制定时噪声的来源（是由于磁层还是内部过程）。 因此，对所提出场景之一的观测确认将为脉冲星引力波发射的物理提供有价值的信息。 显示英文摘要

摘要： Neutron stars emitting continuous gravitational waves may be regarded as gravitational pulsars, in the sense that it could be possible to track the evolution of their rotational period with long-baseline observations of next-generation gravitational wave interferometers. Assuming that the pulsar's electromagnetic signal is tracked and allows us to monitor the pulsar's spin evolution, we provide a physical interpretation of the possible observed correlation between this timing solution and its gravitational counterpart, if the system is also detected in gravitational waves. In particular, we show that next-generation detectors, such as the Einstein Telescope, could have the sensitivity to discern different models for the coupling between the superfluid and normal components of the neutron star and constrain the origin of timing noise (whether due to magnetospheric or internal processes). Observational confirmation of one of the proposed scenarios would therefore provide valuable information on the physics of gravitational wave emission from pulsars.
