Gravitational Radiations from a Spinning Compact Object around a supermassive Kerr black hole in circular orbit

Understand

The gravitational waves and energy radiations from a spinning compact object with stellar mass in a circular orbit in the equatorial plane of a supermassive Kerr black hole are investigated in this paper.

• The effect how the spin acts on energy and angular moment fluxes is discussed in detail.
• The calculation results indicate that the spin of small body should be considered in waveform-template production for the upcoming gravitational wave detections.
• It is clear that when the direction of spin axes is the same as the orbitally angular momentum ("positive" spin), spin can decrease the energy fluxes which radiate to infinity.
