Abstract

We have found a dramatic change in the spectra of late-type M dwarfs at wavelengths shorter than 0.75 microns. Comparisons with synthetic spectra illustrate that this change is well explained by the presence of dust. It thus seems that a substantial part of the long-standing discrepancies between late-type M dwarf models and observations arises from dust as recently proposed by Tsuji, Ohnaka and Aoki (1996a).
