Examining the relationships between colour, $T_{\mathrm{eff}}$, and [M/H] for APOGEE K and M dwarfs

Sarah J. Schmidt, Erika L. Wagoner, Jennifer A. Johnson +4

We present the effective temperatures ($T_{\mathrm{eff}}$), metallicities, and colours in SDSS, 2MASS, and WISE filters, of a sample of 3834 late-K and early-M dwarfs selected from the…
