The MiMeS Project: Current status and recent results

TL;DR

The MiMeS Project studies magnetic fields in massive stars through extensive spectropolarimetric observations, revealing new magnetic stars and advancing understanding of their origin, evolution, and impact.

Contribution

This paper provides an overview of the MiMeS Project's current status, data collection, modeling efforts, and recent significant discoveries in magnetic massive stars.

Findings

Discovered magnetic fields in over a dozen massive stars

Detected magnetic fields in the most rapidly-rotating known magnetic star

Identified the most massive known magnetic star

Abstract

The Magnetism in Massive Stars (MiMeS) Project is a consensus collaboration among many of the foremost international researchers of the physics of hot, massive stars, with the basic aim of understanding the origin, evolution and impact of magnetic fields in these objects. At the time of writing, MiMeS Large Programs have acquired over 1250 high-resolution polarised spectra of about 150 individual stars with spectral types from B5-O4, discovering new magnetic fields in over a dozen hot, massive stars. Notable results include the detection of magnetic fields in the two most rapidly-rotating known magnetic stars, and in the most massive known magnetic star. In this paper we review the structure of the MiMeS observing programs and report the status of observations, data modeling and development of related theory, and review important results obtained so far.
