High-energy radiation from T Tauri stars

TL;DR

This paper models high-energy non-thermal radiation from T Tauri stars, exploring the potential detectability of gamma-ray emissions resulting from magnetic reconnection events and particle acceleration.

Contribution

It introduces a simple model for non-thermal radiation in T Tauri stars and assesses its observability with current gamma-ray telescopes.

Findings

High-energy particles can produce detectable gamma-ray emission.

Magnetic reconnection events are significant sources of particle acceleration.

Potential for future gamma-ray observations of T Tauri stars.

Abstract

T Tauri stars are young, low mass, pre-main sequence stars surrounded by an accretion disk. These objects present strong magnetic activity and powerful magnetic reconnection events. Strong shocks are likely produced in the stellar magnetosphere by such events and charged particles accelerated up to relativistic energies. We present a simple model for the non-thermal radiation generated by high-energy particles in T Tauri stars. We discuss whether this emission is detectable at high energies with the available gamma-ray telescopes.
