THE JINA REACLIB DATABASE: ITS RECENT UPDATES AND IMPACT ON TYPE-I X-RAY BURSTS
- R. Cyburt, A. Amthor, M. Wiescher
- PhysicsThe Astrophysical Journal Supplement Series
- 30 June 2010
We present results from the JINA REACLIB project, an ongoing effort to maintain a current and accurate library of thermonuclear reaction rates for astrophysical applications. Ongoing updates are…
Models for Type I X-Ray Bursts with Improved Nuclear Physics
- S. Woosley, A. Heger, M. Wiescher
- Physics
- 24 July 2003
Multizone models of Type I X-ray bursts are presented that use an adaptive nuclear reaction network of unprecedented size, up to 1300 isotopes, for energy generation and include the most recent…
The Rapid Proton Process Ashes from Stable Nuclear Burning on an Accreting Neutron Star
- H. Schatz, L. Bildsten, A. Cumming, M. Wiescher
- Physics
- 20 May 1999
The temperature and nuclear composition of the crust and ocean of an accreting neutron star depend on the mix of material (the ashes) that is produced at lower densities by fusion of the accreting…
Thorium and Uranium Chronometers Applied to CS 31082-001
- H. Schatz, R. Toenjes, K. Kratz
- Physics
- 20 April 2001
We use the classical r-process model to explore the implications of the recently reported first observation of U in the extremely metal-poor, r-process element-enriched halo star CS 31082-001 for U…

Heating in the Accreted Neutron Star Ocean: Implications for Superburst Ignition
- Sanjib S. Gupta, E. Brown, H. Schatz, P. Moeller, K. Kratz
- Physics
- 29 September 2006
We perform a self-consistent calculation of the thermal structure in the crust of a superbursting neutron star. In particular, we follow the nucleosynthetic evolution of an accreted fluid element…
Explosive Hydrogen Burning during Type I X-Ray Bursts
- J. Fisker, H. Schatz, Friedrich-Karl Thielemann
- Physics
- 13 March 2007
Explosive hydrogen burning in type I X-ray bursts (XRBs) is driven by charged particle reactions creating isotopes with masses up to A ∼ 100. Since charged particle reactions in a stellar environment…
NEW HUBBLE SPACE TELESCOPE OBSERVATIONS OF HEAVY ELEMENTS IN FOUR METAL-POOR STARS
- I. Roederer, J. Lawler, I. Thompson
- Physics, Geology
- 23 October 2012
Elements heavier than the iron group are found in nearly all halo stars. A substantial number of these elements, key to understanding neutron-capture nucleosynthesis mechanisms, can only be detected…
