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.
