On the Observed Mass Distribution of Compact Stellar Remnants in Close Binary Systems and Localizability of Gravitational Energy
There are two new observational facts: (1) the mass spectrum of neutron stars and black hole candidates (or collapsars) shows an evident absence of compact objects with masses within the interval from 2 Mʘ (with a peak for neutron stars about 1.4 Mʘ) to approximately 6 Mʘ, (2) and in close binary stellar systems with a low-massive (about 0.6 Mʘ) optical companion the most probable mass value (the peak in the masses distribution of black hole candidates) is close to 6.7 Mʘ. The problem of the compact objects discrete mass spectra demands some solution both in the context of the supernovae and gamma-ray bursts relation, and in connection with the core-collapse supernovae explosion mechanism itself. In gravidynamics – a totally non-metric scalar-tensor model of gravitational interaction (or a certain modified, extended Feynman approach) with localizable field energy, the total mass of a compact relativistic object is MQ ≈ 6.7 Mʘ with a region filled by matter (quark-gluon plasma, the bag) with radius r* = GMQ/c2 ≈ 10 km. The total (measurable) mass MQ of such an extremely dense object already half consists of the field only, or of its scalar-tensor mixture around. Polarized emission of long gamma-ray bursts, a black-body component in their spectra and other observed properties could be explained by the direct manifestation of a surface of these collapsars.
