MECO In An Exponential Metric

TL;DR

This paper proposes a new model for Magnetic Eternally Collapsing Objects (MECO) using an exponential metric, aiming to better explain their properties and interactions with accretion disks in various astrophysical systems.

Contribution

It introduces an alternative exponential metric for MECO, providing a potentially more accurate framework for understanding their gravitational effects and observational features.

Findings

The exponential metric can produce similar gravitational redshifts as Schwarzschild.

The model offers a unified description of GBHC, AGN, and neutron star systems.

Preliminary results suggest improved consistency with observed phenomena.

Abstract

Magnetic Eternally Collapsing Objects (MECO) have been proposed as the central engines of galactic black hole candidates (GBHC) and supermassive active galactic nuclei (AGN). Previous work has shown that their luminosities and spectral and timing characteristics are in good agreement with observations. These features and the formation of jets are generated primarily by the interactions of accretion disks with an intrinsically magnetic central MECO. The interaction of accretion disks with the anchored magnetic fields of the central objects permits a unified description of properties for GBHC, AGN, neutron stars in low mass x-ray binaries and dwarf novae systems. The previously published MECO models have been based on a quasistatic Schwarzschild metric of General Relativity; however, the only essential feature of this metric is its ability to produce extreme gravitational redshifts. For reasons discussed in this article, an alternative development based on a quasistatic exponential metric is considered here.
