PRELIMINARY ABUNDANCE ANALYSIS OF 9 SUBDWARFS

PRELIMINARY ABUNDANCE ANALYSIS OF 9 SUBDWARFS

We provide parameter and abundance determination of 9 subwarfs including two SMR stars (HD 161797 and HD 182572). These stars show metallicity overabundance in agreement with previous results. Further we plan to carry out the detailed analysis of luminosity, evolutionary status, age and belonging of...
