Radiative properties of thin accretion disks around rotating short-hairy black holes

Abstract

The radiative properties of the accretion disks around rotating short-hairy black holes are studied. The geodesic motion of massive particles in the equatorial planes of short-hairy black holes and impact of the rotation parameter $a$, short-hair parameter $Q$ and power parameter $k$ on the geodesic motion is obtained. Then, we consider thin accretion disks around the short-hairy black holes. The radiative flux densities, effective temperatures, differential and spectral luminosity of the disks are investigated for various specific parameters. The impact of parameters $a,Q,k$ on these properties is also discussed.
