A white dwarf star is important as a distance indicator for the cosmic distances. Should it be in a binary system with another star in mutual orbit about each other, then mass can transfer via magnetic activity from the companion star and the Chandrasekhar limit referring to gravitational collapse of about 1.5...

1. The Parametrisation of the Friedmann Equation

It is well known, that the Radius of Curvature in the Field Equations of General Relativity relates to the Energy-Mass Tensor in the form of the critical density ρ_critical = 3H_o²/8πG and the Hubble Constant H_o as the square of frequency or alternatively as the time differential of frequency df/dt as a cosmically...
