Abstract
According to Oort (1965), the mass density in the solar neighbourhood (inferred from the gravity component normal to the galactic plane) is between 50% and 150% greater than the mass density inferred from non-dwarf stars. One possible explanation for the "missing mass" is an overabundance of faint M-dwarfs (Weistrop 1972), but present indications are that this overabundance is either small (Weistrop 1976; Sanduleak 1976) or non-existent (Faber et al. 1976; Eggen 1976). Nevertheless, Salpeter's initial mass function (Salpeter 1955) suggests that the total mass may be dominated by low mass stars, including masses M ≾ 0.08M_⊙ which never undergo significant hydrogen burning.
