The Solar Neighborhood. II. The First List of Dwarfs with Spectral Types of M7 and Cooler
Abstract
Spectra and finder charts are given for 20 dwarfs having types of M7 or later, and a spectral classification scheme is introduced for types M7 V to M9 V. Three of these dwarfs are later that M9 and have spectra in which VO absorption appears greatly enhanced. First results are also presented for a spectroscopic follow-up of unclassified proper motion targets, begun in an attempt to identify other low-luminosity members of the solar neighborhood.
