An overview of jets and outflows in stellar mass black holes

TL;DR

This chapter reviews the empirical relationship between accretion states and outflows in stellar mass black holes, focusing on jets, winds, and their connection to black hole spin.

Contribution

It systematically summarizes current observational understanding of jet and wind phenomena and explores their links to accretion states and black hole properties.

Findings

Empirical links between X-ray states and radio jets established

Systematic inclusion of accretion disc winds in the framework

Recent efforts to measure jet power and relate it to black hole spin

Abstract

In this book chapter, we will briefly review the current empirical understanding of the relation between accretion state and and outflows in accreting stellar mass black holes. The focus will be on the empirical connections between X-ray states and relativistic (`radio') jets, although we are now also able to draw accretion disc winds into the picture in a systematic way. We will furthermore consider the latest attempts to measure/order jet power, and to compare it to other (potentially) measurable quantities, most importantly black hole spin.
