Abstract
AbstractSpace densities for stars given in the „Catalogue of nearby stars”︁ and in „Nearby star data published 1969—1978”︁ were calculated for the stellar groups listed in Table 1 as a function of the distance from the galactic plane. The stars are symmetrically distributed with respect to the galactic plane. Space densities for giant stars nearer than 22 pc were also computed. The comparison between the luminosity functions of stars nearer than 5 pc and 22 pc shows that the number of M dwarfs up to 22 pc is given uncompletely.
