Toward restrictions on boson stars as black hole mimickers

TL;DR

This paper investigates the potential of boson stars to mimic black holes by analyzing their emission spectra and identifying parameters that enable such mimicking, with implications for astrophysical observations.

Contribution

It provides a detailed analysis of the emission spectra of boson stars and identifies key parameters that could make them indistinguishable from black holes.

Findings

Boson stars can mimic black hole emission spectra under certain conditions.

Specific parameter ranges allow boson stars to act as black hole mimickers.

The study offers a framework to differentiate boson stars from black holes observationally.

Abstract

The status of boson stars as black hole mimickers is presented. We focus on the analysis of the emission spectrum of a simple accretion disk model. We describe the free parameters that allow a boson star to become a black hole mimicker and present an example of a particular astrophysical case.
