    • Probing M subdwarf metallicity with an esdK5+esdM5.5 binary 

      Pavlenko, Ya. V.; Zhang, Z. H.; Gálvez-Ortiz, M. C.; Kushniruk, I. O.; Jones, H.R.A. (2015-10-15)
      We present a spectral analysis of the binary G 224-58 AB that consists of the coolest M extreme subdwarf (esdM5.5) and a brighter primary (esdK5). This binary may serve as a benchmark for metallicity measurement calibrations ...
