Dependence of S-Process Nucleosynthesis in Massive Stars on Triple-Alpha and 12C(a,g)16O Reaction Rate Uncertainties
Clarisse Tur, Alexander Heger, Sam M. Austin
We have studied the sensitivity of s-process nucleosynthesis in massive stars to +/- 2 sigma variations in the rates of the triple alpha and 12C(a,g)16O reactions. We simulated the…
A Bitter Pill: The Primordial Lithium Problem Worsens
Richard H. Cyburt, Brian D. Fields, Keith A. Olive
The lithium problem arises from the significant discrepancy between the primordial 7Li abundance as predicted by BBN theory and the WMAP baryon density, and the pre-Galactic lithiu…
X-ray Spectral Identification of Three Candidate Quiescent Low-Mass X-ray Binaries in the Globular Cluster NGC 6304
Sebastien Guillot, Robert E. Rutledge, Lars Bildsten +3
We report the search for low-mass X-ray binaries in quiescence (qLMXBs) in the globular cluster NGC 6304 using XMM observations. We present the spectral analysis leading to the ide…
The Reduction of the Electron Abundance during the Pre-explosion Simmering in White Dwarf Supernovae
David A. Chamulak, Edward F. Brown, F. X. Timmes +1
Prior to the explosion of a carbon-oxygen white dwarf in a Type Ia supernova there is a long "simmering," during which the 12C + 12C reaction gradually heats the white dwarf on a l…
First superburst from a classical low-mass X-ray binary transient
L. Keek, J. J. M. in 't Zand, E. Kuulkers +3
We report the analysis of the first superburst from a transiently accreting neutron star system with the All-Sky Monitor (ASM) on the Rossi X-ray Timing Explorer. The superburst oc…
Nucleosynthesis in the Early Galaxy
F. Montes, T. C. Beers, J. Cowan +8
Recent observations of r-process-enriched metal-poor star abundances reveal a non-uniform abundance pattern for elements . Based on non-correlation trends between elementa…
