discusses the Rindler horizons of an observer in a radial, locally Rindler trajectory (i.e. hyperbolic in a local inertial frame) in the Schwarzschild spacetime. As in the flat case these trajectories are defined by constant norm of the 4-acceleration and zero 4-rotation.

Note that a stationary observer in a Schwarzschild spacetime is such an observer.

Meanwhile the equations of the future (past) Rindler horizon for a given locally Rindler trajectory can be determined from the null geodesics with the same intercept with future (past) null infinity.
