The evolution of magnetic stars in a single-age population

TL;DR

This paper investigates how fossil magnetic fields influence the evolution of massive stars and their end states, using population modeling to incorporate magnetic effects into stellar evolution.

Contribution

It introduces a population study using MESA tracks that include magnetic mass-loss quenching, advancing understanding of magnetic star evolution.

Findings

Magnetic fields affect stellar mass loss and evolution.

Fossil fields influence the late stages of stellar evolution.

Preliminary results suggest magnetic effects are significant in population models.

Abstract

Observational and theoretical work has now established that the fossil fields of magnetic massive stars are surviving remnants from an earlier event, or an earlier evolutionary phase. However, many important questions remain regarding the effects of these fields on the late stages of stellar evolution, as well as their impact on the core-collapse mechanism and the formation of exotic compact objects such as magnetars and gravitational wave progenitors. There is currently a critical need to incorporate the impact of fossil fields in models of the structure and evolution of magnetic stars, and to determine the evolutionary history of magnetic massive stars. We present a preliminary population study of a cluster of co-evolving stars based on MESA evolutionary tracks that account for the effect of magnetic mass-loss quenching.
