Comment on Perihelion Advance due to Cosmological Constant
We comment on the recent paper “Note on the perihelion/periastron advance due to cosmological constant” by H. Arakida (Int. J. Theor. Phys. 52, 1408 (2013)) and provide simple derivations of both the main result of this paper and of the Adkins–McDonnell’s precession formula, on which this main result is based.
