Static boson stars in the Einstein-Friedberg-Lee-Sirlin theory and their astrophysical images
We investigate static boson star solutions in the so-called Einstein-Friedberg-Lee-Sirlin (E-FLS) theory and perform a complete analysis of the solution space in this model. We study the phenomenological aspects of E-FLS stars with an emphasis on the analysis of circular timelike orbits and circular photon orbits. In order to study the astrophysical signatures of such stars, their images were obtained under the assumption that they are surrounded by a geometrically thin accretion disk. Here we consider two different accretion disk models, namely the optically thin and optically thick disk models. We present a selection of our findings for the astrophysical images of E-FLS stars and discuss their relevance as possible black hole mimickers.
