Why are so many primitive stars observed in the Galaxy halo?

TL;DR

This paper argues that the observed primitive stars in the Galaxy halo, such as SDSS J102915+172927, can be explained by hydrogravitational dynamics (HGD) theory, which posits early formation of stars from primordial gas planets, contrasting with standard CDM models.

Contribution

The paper introduces HGD theory as an alternative to CDM, explaining the formation of primitive stars from primordial gas planets in early universe clumps, challenging traditional views on first star formation.

Findings

Primitive halo stars can be explained by HGD theory.

HGD predicts small, long-lived first stars in the Galaxy halo.

Standard CDM theory cannot account for the observed low lithium in some stars.

Abstract

Small values of lithium observed in a small, primitive, Galaxy-Halo star SDSS J102915 + 172927 cannot be explained using the standard cold dark matter CDM theory of star formation, but are easily understood using the Gibson/Schild 1996 hydrogravitationaldynamics (HGD) theory. From HGD, primordial H-4He gas fragments into Earth-mass planets in trillion-planet proto-globular-star-cluster (PGC) clumps at the 300 Kyr time of transition from the plasma epoch, soon after the big bang. The first HGD stars formed from pristine, frictionally-merging, gas-planets within the gently stressed clumps of the early universe, burning most available lithium in brown-dwarfs and hot-stars before creating metals that permit cooler burning. The Caffau halo star is a present day example. CDM first stars (Population III) were massive and promptly exploded, reionizing the gas of the universe and seeding it with metals, thus making the observed star unexplainable. From HGD, CDM and its massive first stars, and re-ionization by Pop III supernovae, never happened. All stars are formed from planets in primordial clumps. HGD first stars (Pop III) were small and long-lived, and the largest ones were hot. We suggest such small HGD (Pop III) stars still form in the gently stressed Galaxy halo.
