Chaotic von Zeipel-Lidov-Kozai Oscillations of Binary System around Rotating Supermassive Black Hole
Kei-ichi Maeda, Priti Gupta, Hirotada Okawa
In this paper, we investigate the dynamics of a binary system that orbits a rotating supermassive black hole. Our approach employs Fermi-Walker transport to construct a local inert…
Dynamics of Binary System around Supermassive Black Hole
Kei-ichi Maeda, Priti Gupta, Hirotada Okawa
We discuss motion of a binary system around a supermassive black hole. Using Fermi-Walker transport, we construct a local inertial reference frame and set up a Newtonian binary sys…
Resonant jumps induced by stationary tidal perturbation: a two-for-one deal
Priti Gupta, Takafumi Kakehi, Takahiro Tanaka
Extreme-mass-ratio inspirals (EMRIs) are promising target sources for space-based interferometers such as LISA, Taiji, and Tianqin. Depending on the astrophysical environment, such…
Modeling transient resonances in extreme-mass-ratio inspirals
Priti Gupta, Lorenzo Speri, Béatrice Bonga +2
Extreme-mass-ratio inspirals are one of the most exciting and promising target sources for space-based interferometers (such as LISA, TianQin). The observation of their emitted gra…
Importance of tidal resonances in extreme-mass-ratio inspirals
Priti Gupta, Béatrice Bonga, Alvin J. K. Chua +1
Extreme mass ratio inspirals (EMRIs) will be important sources for future space-based gravitational-wave detectors. In recent work, tidal resonances in binary orbital evolution ind…
Post-Newtonian Kozai-Lidov Mechanism and its Effect on Cumulative Shift of Periastron Time of Binary Pulsar
Haruka Suzuki, Priti Gupta, Hirotada Okawa +1
We study the Kozai-Lidov mechanism in a hierarchical triple system in detail by the direct integration of the first-order post Newtonian equations of motion. We analyse a variety o…
Gravitational Waves from Hierarchical Triple Systems with Kozai-Lidov Oscillation
Priti Gupta, Haruka Suzuki, Hirotada Okawa +1
We study gravitational waves from a hierarchical three-body system up to first-order postNewtonian approximation. Under certain conditions, the existence of a nearby third body can…
Cumulative Shift of Periastron Time of Binary Pulsar with Kozai-Lidov Oscillation
Haruka Suzuki, Priti Gupta, Hirotada Okawa +1
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.…
