The CARMENES search for exoplanets around M dwarfs: Diagnostic capabilities of strong K I lines for photosphere and chromosphere

There are several strong K  I lines found in the spectra of M dwarfs, among them the doublet near 7700 Å and another doublet near 12 500 Å. We study these optical and near-infrared doublets in a sample of 324 M dwarfs, observed with CARMENES, the high-resolution optical and near-infrared spectrograp...
