The Na i D resonance lines in main-sequence late-type stars
We study the sodium D lines (D1: 5895.92 Å; D2: 5889.95 Å) in late-type dwarf stars. The stars have spectral types between F6 and M5.5 (B - V between 0.457 and 1.807) and metallicity between and 0.6. We obtained medium-resolution echelle spectra using the 2.15-m telescope at the Argentinian observat...
