General Description

• OBJECTIVES :
  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 with FEROS, 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
   to establish a spectroscopic metallicity estimator. The M components are much fainter
   than their primeries and we will observe them with UVES.
  
  OBSERVATIONS :
  -Stars to observe are easy to identify on the provided finding charts. 
  -If a doubt arises because the central star turn out to be a binary (when the finding
   chart has not a resolution good enough), then always observe the brightest star.
  -Sometimes a close compagnon to the brightest star makes the guiding difficult.
   The observer should guide with another star, maybe with the help of the WFI camera.
