The Light Elements Be and B as Stellar Chronometers in the Early Galaxy

  title={The Light Elements Be and B as Stellar Chronometers in the Early Galaxy},
  author={Timothy C. Beers and Takeru K. Suzuki and Yuzuru Yoshii},
  journal={arXiv: Astrophysics},
Recent detailed simulations of Galactic Chemical Evolution have shown that the heavy elements, in particular [Fe/H], are expected to exhibit a weak, or absent, correlation with stellar ages in the early Galaxy due to the lack of efficient mixing of interstellar material enriched by individual Type II supernovae. A promising alternative "chronometer" of stellar ages is suggested, based on the expectation that the light elements Be and B are formed primarily as spallation products of Galactic…

Light Elements in the Universe
Due to their production sites, as well as to how they are processed and destroyed in stars, the light elements are excellent tools to investigate a number of crucial issues in modern astrophysics:
Early star formation in the Galaxy from beryllium and oxygen abundances
We investigate the evolution of the star formation rate in the early Galaxy using beryllium and oxygen abundances in metal poor stars. Specifically, we show that stars belonging to two previously
Beryllium abundances and star formation in the halo and in the thick disk
Context. Beryllium is a pure product of cosmic ray spallation. This implies a relatively simple evolution in time of the beryllium abundance and suggests its use as a time-like observable. Aims. Our
Beryllium and the formation of the Thick Disk and of the Halo
Abstract We use Beryllium to investigate star formation in the early Galaxy. Be has been demonstrated to be a good indicator of time in these early epochs. By analyzing the so-far largest sample of
Beryllium abundances and the formation of the halo and the thick disk
Abstract The single stable isotope of beryllium is a pure product of cosmic-ray spallation in the ISM. Assuming that the cosmic-rays are globally transported across the Galaxy, the beryllium
The origin of the light elements in the early Universe
Shortly after World War II, George Gamov and his collaborators (Alpher et al. 1948) considered the possibility that all chemical elements might have been generated by a succession of nucleon capture
Beryllium in turnoff stars of NGC 6397: Early Galaxy spallation, cosmochronology and cluster formation ,
We present the first detection of beryllium in two turnoff stars of the old, metal-poor globular cluster NGC 6397. The beryllium lines are clearly detected and we determine a mean beryllium abundance
Beryllium abundance in turn-off stars of NGC 6752
Aims: To measure the beryllium abundance in two TO stars of the Globular Cluster NGC 6752, one oxygen rich and sodium poor, the other presumably oxygen poor and sodium rich. Be abundances in these


The First Generation of Stars: First Steps toward Chemical Evolution of Galaxies
We argue that extreme metal-poor stars show a high dispersion in metallicity, because their abundances are the outcome of very few supernova events. Abundance anomalies should appear because of the
Chemical Evolution of the Galactic Halo through Supernova-induced Star Formation and Its Implication for Population III Stars
A model for Galactic chemical evolution, driven by supernova-induced star formation, is formulated and used to examine the nature of the Galactic halo at early epochs. In this model, new stars are
Extremely Metal-Poor Stars. II. Elemental Abundances and the Early Chemical Enrichment of The Galaxy*
We have obtained high-resolution spectra of 23 very metal-poor stars and present an abundance analysis for 19 of these for elements between Mg and Eu. The sample comprises roughly equal numbers of
A model of supernova-driven chemical evolution of the Galactic halo, recently proposed by Tsujimoto, Shigeyama, & Yoshii, is extended in order to investigate the evolution of light elements such as
Beryllium Abundances in Halo Stars from Keck/HIRES Observations
We have determined the abundance of Be in stars with an array of metal abundances in order to enhance our understanding of the chemical evolution of the Galaxy, cosmic-ray theory, and cosmology.
Subdwarf studies. III, The halo metallicity distribution
We have constructed the metallicity distribution of a sample of 372 kinematically selected halo stars, most having spectroscopically determined abundances, drawn from our southern subdwarf study and
