The origin of primordial dwarf stars and baryonic dark matter.

HANSEN B.M.S.

Abstract (from CDS):

I present a scenario for the production of low-mass, degenerate dwarfs of mass greater than 0.1 M_☉ via the mechanism of Lenzuni, Chernoff, & Salpeter. Such objects meet the mass limit requirements for halo dark matter from microlensing surveys while circumventing the chemical evolution constraints on normal white dwarf stars. I describe methods to observationally constrain this scenario and suggest that such objects may originate in small clusters formed from the thermal instability of shocked, heated gas in dark matter halos, such as suggested by Fall & Rees for globular clusters.
