With the advent of more powerful instruments such as the Hubble Space Telescope, a wealth of new observational information will be forthcoming. Thus it is imperative that refinements to theoretical models keep pace with t

Index for 2.1 (System No., References),cal luminosity functions for both disk and halo white dwarfs, based on those diagrams, are then described. We conclude that faint, still undetected white dwarfs are unlikely to be major contributors to baryonic dark matter, neither in the disk nor in the halo of the Galaxy.

In this case we may see them as low-mass X-ray binary systems and then millisecond pulsars or else

Index for 2.2 (System No., References),binary evolution is described and illustrated for simple binary star birthrate models. Owing to selection effects, the physics of the evolving distribution, and the paucity of well-selected data, I unfortunately conclude that no limits on the mass of dark objects are yet possible. Finally, I present

The mass-to-light ratio of the luminous material, corrected for variations in the present rate of star formation, is remarkably constant and in agreement with classical population synthesis models.

This subject is approached historically by considering the cosmic history of the quasar population. The evidence for massive black holes in the centres of some nearby galaxies is reviewed. Some i

The cooled product is not yet observed but is proposed to be some form of low-mass star (perhaps brown dwarf or even jupiter-mass objects). Cooling flows must form baryonic dark matter. A scenario for low-mass star formation in a cooling flow is presented here. The main
