The r-process and neutrino-heated supernova ejecta
As a neutron star is formed by the collapse of the iron core of a massive star, its Kelvin-Helmholtz evolution is characterized by the release of gravitational binding energy as neutrinos. TheExpand

Neutron capture elements in s-process-rich, very metal-poor stars
We report abundance estimates for neutron capture elements, including lead (Pb), and nucleosynthesis models for their origin, in two carbon-rich, very metal-poor stars, LP 625-44 and LP 706-7. TheseExpand

Observation of interstellar lithium in the low-metallicity Small Magellanic Cloud
The primordial abundances of light elements produced in the standard theory of Big Bang nucleosynthesis (BBN) depend only on the cosmic ratio of baryons to photons, a quantity inferred fromExpand

Mass-Radius Relation for Magnetic White Dwarfs
Recently, several white dwarfs with very strong surface magnetic fields have been observed. In this paper we explore the possibility that such stars could have sufficiently strong internal fields toExpand

The r-Process in Neutrino-driven Winds from Nascent, ``Compact'' Neutron Stars of Core-Collapse Supernovae
We present calculations of r-process nucleosynthesis in neutrino-driven winds from the nascent neutron stars of core-collapse supernovae. A full dynamical reaction network for both the α-richExpand

Flash-Driven Convective Mixing in Low-Mass, Metal-deficient Asymptotic Giant Branch Stars: A New Paradigm for Lithium Enrichment and a Possible s-Process
We have calculated models for low-mass, metal-deficient ([Fe/H] = -2.7) stars from the zero-age main sequence through the thermally pulsing asymptotic giant branch (TP-AGB) phase. We confirm that theExpand

Probing the early universe: A Review of primordial nucleosynthesis beyond the standard Big Bang
Abstract The scientific literature is rich with studies of non-standard primodial nucleosynthesis. We review a number of these variants on the simplest standard big bang (SBB) nucleosynthesis modelExpand

Inhomogenous Chemical Evolution of the Galactic Disk
We present analytical models for inhomogeneous chemical evolution (ICE) of systems in which the star formation history resembles a series of bursts, localized in space and/or time, with intermittentExpand

Production of Li, Be \& B from Baryon Inhomogeneous Primordial Nucleosynthesis
We investigate the possibility that inhomogeneous nucleosynthesis may eventually be used to explain the abundances of \li6, \be9 and B in population II stars. The present work differs from previousExpand
