Variability of young stellar objects: accretion, disks, outflows and magnetic activity

TL;DR

This review discusses the variability of young stellar objects, focusing on magnetic activity, accretion, disks, and outflows, highlighting their roles in stellar evolution and observational characteristics.

Contribution

It provides a comprehensive overview of the different sources of variability in young stellar objects, integrating magnetic activity with disk-related processes.

Findings

Magnetic activity influences variability in young stars.

Disk accretion and outflows are key variability drivers.

Variability characteristics help understand stellar evolution.

Abstract

This article represents a short review of the variability characteristics of young stellar objects. Variability is a key property of young stars. Two major origins may be distinguished: a scaled-up version of the magnetic activity seen on main-sequence stars and various processes related to circumstellar disks, accretion and outflows.
