Accretion-caused deceleration of a gravitationally powerful compact stellar object moving within a dense Fermi gas

TL;DR

This paper investigates how a dense Fermi gas medium causes deceleration of a massive compact stellar object through accretion, providing analytical and numerical estimates of this effect.

Contribution

It introduces a model for accretion-induced deceleration of compact objects in Fermi gases, with analytical and numerical analysis of the phenomenon.

Findings

Deceleration effect is significant in dense Fermi gases.

Analytical estimates match numerical simulations.

The effect depends on the properties of the Fermi gas.

Abstract

We consider accretion-caused deceleration of a gravitationally-powerful compact stellar object traveling within a cold Fermi-gas medium. We provide analytical and numerical estimates of the effect manifestation.
