Query: The Incidence of Magnetic Fields in Massive Stars: An Overview of the
  MiMeS Survey Component   With only a handful of known magnetic massive stars, there is a troubling
deficit in the scope of our knowledge of the influence of magnetic fields on
stellar evolution, and almost no empirical basis for understanding how fields
modify mass loss and rotation in massive stars. Most remarkably, there is still
no solid consensus regarding the origin physics of these fields - whether they
are fossil remnants, or produced by contemporaneous dynamos, or some
combination of these mechanisms. This article will present an overview of the
Survey Component of the MiMeS Large Programs, the primary goal of which is to
search for Zeeman signatures in the circular polarimetry of massive stars
(stars with spectral types B3 and hotter) that were previously unknown to host
any magnetic field. To date, the MiMeS collaboration has collected more than
550 high-resolution spectropolarimetric observations with ESPaDOnS and Narval
of nearly 170 different stars, from which we have discovered 14 new magnetic
stars.
