Cumulative Shift of Periastron Time of Binary Pulsar with Kozai-Lidov Oscillation

26 Apr 2019 Suzuki Haruka Gupta Priti Okawa Hirotada Maeda Kei-ichi

We study a hierarchical triple system with the Kozai-Lidov mechanism, and analyse the cumulative shift of periastron time of a binary pulsar by the emission of gravitational waves. Time evolution of the osculating orbital elements of the triple system is calculated by directly integrating the first-order post-Newtonian equations of motion... (read more)
