Appendix A: Spectra of the candidate Hα emission-line stars

In Fig. A1 we present the full spectra of the M-dwarf stars in our sample. In Fig. A2 we show the spectrum of the earlier type star.

a) (Top panel) Spectrum of candidate Hα emission-line star Ha1. The locations of the TiO and CaH absorption bands are indicated below the spectrum, as are the expected locations of several features. Telluric lines are marked with a crossed circle. b) (Bottom panel) as a), but for candidate Hα emission-line star Ha2.
