TL;DR
This paper investigates dark energy accretion onto black holes within a Schwarzschild-de Sitter spacetime, demonstrating that current observational data align with results obtained without a cosmological constant.
Contribution
It extends previous models by including a positive cosmological constant, analyzing its effects on dark energy accretion onto black holes.
Findings
Results match previous models without cosmological constant
Current observational data support the model with a positive cosmological constant
Dark energy accretion effects are consistent across different spacetime descriptions
Abstract
In this paper we study the accretion of dark energy onto a black hole in the cases that dark energy is equipped with a positive cosmological constant and when the space-time is described by a Schwarzschild-de Sitter metric. It is shown that, if confronted with current observational data, the results derived when no cosmological constant is present are once again obtained in both cases.
