RELATION BETWEEN PLANETARY NUCLEI AND QUASARS

In a previous paper we have shown that a continuity exists in the spectra of O VI sequence planetary nuclei (Smith and Aller, 1969) Sanduleak stars and 10 quasars. From this we were led to infer that these are related objects. We shall try to estimate the proper motions of quasars from this link.

Two factors have first to be considered:

  1. The distribution of quasars in the galaxy.
  2. The space density of quasars
