Shane/Kast red optical spectrum of TOI-2096 (black), compared to an M4 template (Kesseli et al. 2017, magenta). Spectra are normalized in the 7400–7500 A region, and major absorption features are labeled, including resolved lines. The inset box shows a close-up of the region hosting Hα and Li I features. The former is obscured by an unfortunate cosmic ray strike (unmasked spectral data in grey); the latter is not detected.
