Quasi-periodic oscillations from the accretion disk around rotating traversable wormholes

Understand

We study the quasi-periodic oscillations from the accretion disk around rotating traversable wormholes by means of the resonance models.

• We investigate the linear stability of the circular geodesic orbits in the equatorial plane for a general class of wormhole geometries deriving analytical expressions for the epicyclic frequencies.
• Since wormholes can often mimic black holes in the astrophysical observations, we analyze the properties of the quasi-circular oscillatory motion in comparison with the Kerr black hole.
• We demonstrate that wormholes possess distinctive features, which can be observationally significant.
