Abstract

We propose a simple calculation to obtain the gravitational lensing on rotating stars. The calculation has been made by using a Lagrangian of Kerr metric and getting  for deflection angle. The calculation has been reduced to slow-rotating stars and equatorials case ()  for maximum deflection angle.
