MiMeS Motivation


Massive stars are those with initial masses on the main sequence above about 8 solar masses, leading to core-collapse (or pair-instability) supernovae. They dominate the ecology of the Universe as "cosmic engines" via their extreme output in radiation and particles - not only as supernovae, but also during their entire lifetimes - with far-reaching consequences. 

Although the existence of magnetic fields in massive stars is no longer in question, our knowledge of the basic statistical properties of massive star magnetic fields is seriously incomplete. There is a troubling deficit in our knowledge of the scope of the influence of fields on massive star evolution, and almost no empirical basis for how fields modify mass loss. The MiMeS project represents a consensus effort by an international team of recognized researchers who have compiled a strategic sample of sources to address these outstanding issues.

Magnetism in Massive Stars

The MiMeS Project

The basic aim of MiMeS is to exploit the unique characteristics of the ESPaDOnS, Narval and HARPSpol spectropolarimeters to obtain critical missing information about the poorly-studied magnetic properties of massive stars, to confront current models and to guide theory. The four primary science drivers are:

  1. Physics of fossil stellar magnetic fields

  2. Physics of winds and magnetospheres of hot stars

  3. Stellar rotational evolution and magnetic braking

  4. Stellar evolution and origin of neutron star magnetic fields
