Estimated Total Execution Time (hours, including overheads)
General Description
Our purpose is to determine the metallicity of an extention of an M-dwarf
sample. To do this, we have selected a sample of separated visual binaries with
FGK dwarfs primaries and M-dwarf secondaries. The determination of the primary star
gives a good estimate of the metallicity of the secondary.
Our observing strategy consists in observing all the primary stars of these couples
with a high signal-to-noise ratio withe FEROS (2.2m/La Silla), determining accurately
the metallicity of the primary component (and by hypothesis of the secondary), by
high resolution spectroscopy. This approach will overcome the difficulty of direct
metallicity measurement of M dwarfs and give a straightforward extension to our
photometric calibration of M-dwarf metallicity.
The second aspect of our observing strategy consists in also observing the M components
with UVES to establish a spectroscopic metallicity estimator. The secondaries of
our sample span a large V-magnitude domain. We have scaled the exposure time according
to their V magnitude. We will observe them when brighter than V=15 in order to record
spectra with 30

files to your OBs?
If you have preferences which OBs should be executed first, did you make
use of the User Priority field in the OBs ?
If this is a run that requires coordinated observations with other facilities,
did you give proper instructions in the Time-Critical Aspects Section ?
If you need secondary guiding, are there suitable objects within 30 arcsec
from your target ?
