Abstract:
The MiMeS (Magnetism in Massive Stars) project is a large-scale,
high-resolution, sensitive spectropolarimetric investigation of the
magnetic properties of O- and early B-type stars. Initiated in 2008
and completed in 2013, the project was supported by three Large
Program allocations, as well as various programmes initiated by
independent principal investigators, and archival resources.
Ultimately, over 4800 circularly polarized spectra of 560 O and B
stars were collected with the instruments ESPaDOnS (Echelle
SpectroPolarimetric Device for the Observation of Stars) at the
Canada-France-Hawaii Telescope, Narval at the Telescope Bernard Lyot
and HARPSpol at the European Southern Observatory La Silla 3.6m
telescope, making MiMeS by far the largest systematic investigation of
massive star magnetism ever undertaken. In this paper, the first in a
series reporting the general results of the survey, we introduce the
scientific motivation and goals, describe the sample of targets,
review the instrumentation and observational techniques used, explain
the exposure time calculation designed to provide sensitivity to
surface dipole fields above approximately 100G, discuss the
polarimetric performance, stability and uncertainty of the
instrumentation, and summarize the previous and forthcoming
publications.
Description:
To initiate the observational component of the MiMeS project, the
collaboration was awarded a 640 hour Large Program (LP) with ESPaDOnS.
This award was followed by LP allocations with Narval (137 nights,
or 1213 hours), and with HARPSpol (30 nights , or 280 hours).
The TC sample (summarized in Table 4) consists of stars that were
established or suspected to be magnetic at the beginning of the
project. The majority of these stars are confirmed period ic variables
with periods ranging from approximately 1 d to 1.5 years, with the
majority having a period of less than 10 days so that they are
suitable candidates for observational monitoring and mapping.
