Abstract:
The massless particle motion around rotating wormhole in the presence of
plasma environment has been studied. It has been shown that the presence
of the plasma decreases the inner radius of the circular orbits of
photons around rotating wormhole. The shadow cast by rotating wormhole
surrounded by inhomogeneous plasma with the radial power-law density has
been explored. It has been shown that the shape and size of the wormhole
shadow is distorted and changed depending on i) plasma parameters, ii)
wormhole rotation and iii) inclination angle between observer plane and
axis of rotation of wormhole. As an example we have considered an
inverse radial distribution of the plasma density and different types of
the wormhole solution.
