Pseudoenergy, Superenergy, and Energy Radiation via Gravitational Waves in General Relativity

Abstract

For slowly spinning matter the rate of energy loss via radiation of gravitational waves is estimated in General Relativity (GR) within a generally covariant superenergy approach. This estimation differs from Einstein's Quadrupole Formula (EQF) by a suppression factor ($Π\ll1$). For a symmetric two-body-like distribution of scalar matter $Π$ is estimated to be $\ll(v/c)^2(r/R)^2$, where $v$ is orbital velocity of the bodies, $c$ - velocity of light, $r$ - radius of each body, and $R$ -- the inter-body distance. This contradiction with EQF is briefly discussed.
