Secular evolution of orbital parameters for general bound orbits in Kerr spacetime
Norichika Sago, Ryuichi Fujita, Soichiro Isoyama +1
We analytically derive the secular changes of the orbital parameters, i.e., energy, angular momentum, and Carter constant, for general bound orbits in Kerr spacetime, at leading or…
Adiabatic waveforms from extreme-mass-ratio inspirals: an analytical approach
Soichiro Isoyama, Ryuichi Fujita, Alvin J. K. Chua +3
Scientific analysis for the gravitational-wave detector LISA will require theoretical waveforms from extreme-mass-ratio inspirals (EMRIs) that extensively cover all possible orbita…
Scope out multiband gravitational-wave observations of GW190521-like binary black holes with space gravitational wave antenna B-DECIGO
Hiroyuki Nakano, Ryuichi Fujita, Soichiro Isoyama +1
The gravitational wave event, GW190521 is the most massive binary black hole merger observed by ground-based gravitational wave observatories LIGO/Virgo to date. While the observed…
Extreme mass ratio inspirals on the equatorial plane in the adiabatic order
Ryuichi Fujita, Masaru Shibata
We compute gravitational waves from inspiraling stellar-mass compact objects on the equatorial plane of a massive spinning black hole (BH). Our inspiral orbits are computed by taki…
