Scientific paper

An extensive analysis of the stellar distribution in the galactic spheroid, and the faint end of the local luminosity function, is currently underway using automated photographic photometry supplemented by spectroscopic, infrared and kinematic studies. Results from the first two of ten fields are reviewed. The survey is complete to MV = ≡19. The luminosity function of main sequence stars shows a broad maximum near MV ≡ +13, and a small decline to fainter magnitudes. The total mass near the Sun is ≡0.04 M_sun; pc-3. The infrared data provide effective temperatures and confirm that all known M dwarfs lie near the theoretical hydrogen burning main sequence. No "black dwarfs" are known.
