Parkes observations for project P455 semester 2020OCTS_06

This project is to continue timing and profile studies of the first double-pulsar system, a unique laboratory for gravitational physics. Recent results, including the first measurements of higher-order light-propagation effects and of the relativistic deformation of the orbit, highlight the importance of a long term observational campaign for this remarkable system. The main aims of this proposal are to exploit the high sensitivity of the UWL receiver to provide the strongest tests to date for general relativity and to measure for the first time the moment-of-inertia of a neutron star. Additionally, we will search for the reappearance of the B pulsar.

本项目旨在延续对首个双脉冲星系统的计时与轮廓研究——该系统是引力物理领域的独特实验室。近期研究成果（包括首次测量高阶光传播效应及轨道的相对论性形变）凸显了针对这一卓越系统开展长期观测计划的重要性。本提案的核心目标在于利用UWL接收器的高灵敏度，开展迄今为止最严格的广义相对论测试，并首次测量中子星的转动惯量（moment-of-inertia）。此外，我们将搜寻B脉冲星的重现。
