Orbital Mechanics & Pulsating Mass
This paper addresses astrophysicists and relativists. It solves the orbital mechanics of variable-mass Keplerian systems under flat, 3D Euclidean space. It demonstrates that perihelion precession is driven by velocity-dependent mass-pulsation hysteresis (

On Hooke's 1685 Manuscript on Orbital Mechanics
Historia Mathematica, 1998 This ``Letter to the Editor'' is a response to Herman Erlichson's critique of the author's analysis of a manuscript by Robert Hooke, dated September 1685, which describes a geometrical construction for orbital dynamics. In order to provide additional evidence for his standpoint, the author demonstrates that Hooke's construction can readily be seen to ...
