Jets from young stars and brown dwarfs

TL;DR

This paper reviews the current understanding of jets from young stars and brown dwarfs, highlighting their properties, significance in star formation, and recent discoveries of brown dwarf outflows.

Contribution

It provides a comprehensive summary of jets from young stars and presents new insights into jets from brown dwarfs, an area with limited observational data.

Findings

Jets are crucial in star formation processes.

Brown dwarfs can also produce outflows similar to stars.

Observed properties of brown dwarf jets are comparable to low-mass protostellar outflows.

Abstract

The protostellar outflow mechanism operates for a significant fraction of the pre-main sequence phase of a solar mass star and is thought to have a key role in star and perhaps even planet formation. This energetic mechanism manifests itself in several different forms and on many scales. Thus outflow activity can be probed in numerous different regimes from radio to X-ray wavelengths. Recent discoveries have shown that it is not only solar mass stars that launch outflows during their formation but also the sub-stellar brown dwarfs. In this article what is currently known about jets from young stars is summarised, including an outline of why it is important to study jets. The second part of this article is dedicated to jets from young brown dwarfs. While only a small number of brown dwarf outflows have been investigated to date, interesting properties have been observed. Here observations of brown dwarf outflows are described and what is currently known of their properties compared to low mass protostellar outflows.
