A Global Energetic Model for Microquasars: preliminary results and spectral energy distributions

TL;DR

This paper introduces a theoretical model for microquasars that unifies their spectral states by combining accretion disk physics with jet launching mechanisms, and presents preliminary spectral energy distribution results for a specific source.

Contribution

It develops a comprehensive model integrating a magnetized jet-emitting disk with spectral state predictions and initial SED reproductions for microquasars.

Findings

Reproduces known accretion disk solutions including stable and unstable states.

Provides initial spectral energy distribution fitting for XTE J1118+480.

Suggests a unified framework for microquasar spectral states.

Abstract

We present preliminary results and observables from a model of microquasar based on a theoretical framework where stationary, powerful, compact jets are launched and then accelerated from an inner magnetized disk. This model aim at providing a consistent picture of microquasars in all their spectral states. It is composed of an outer standard accretion disk down to a variable transition radius where it changes to a magnetized disk, called the Jet Emitting Disk (JED). The theoretical framework providing the heating, we solve the radiative equilibrium and obtain the JED structure. Our JED solutions are rich, and reproduce the already known scheme where a cold optically-thick and a hot optically-thin solutions bracket a thermally unstable one. We present the model and preliminary results, whith a first attempt at reproducing the observed SED of XTE J1118+480.
