2011ApJ...741L..31P Cause of Spiral Galaxy Rotation Rates: A Massive Graviton Pestana, Jose Luis G.; Eckhardt, Donald H. Abstract. We attribute the observed rotational velocity profiles of spiral galaxy disks to a combination of Newtonian and exponential gravitational potentials. We offer a novel, yet perfectly plausible, Lag>ian from which the exponential potential is derived. The exponential potential is defined by two universal constants (corresponding to a coupling constant and a graviton mass) that we determine from our sample of 12 THINGS disks. All velocity profile fits are excellent. Key words: dark matter, elementary particles, galaxies: dwarf, galaxies: kinematics and dynamics, galaxies: spiral, gravitation
