Caveat in Detailed Chemical Analysis of Early-M-dwarfs

[Abstract1]

We verified our chemical analysis method by the comparison between the chemical abundances of mid-M dwarfs (Teff ~
3200 K) we determined and those of FGK-type stars which constitute the binary systems with the mid-M dwarfs. However, we subsequently tried applying the same comparison to an early-M dwarf (Teff ~ 3700 K) and found that the error size of abundances become much larger in such temperature regime. We suspect that it is because the degrees of ionization of dominant metals change most drastically just around the temperature. We report the situation.
