The jina reaclib database: its recent updates and impact on type-i x-ray bursts

TL;DR: The JINA REACLIB project as mentioned in this paper maintains a library of thermonuclear reaction rates for astrophysical applications, which are transparently documented and version tracked, and any set of rates is publicly available and can be downloaded via a web interface at http://groups.nscl.msu.edu/jina/reaclib/db/.
Journal ArticleDOI

Models for type I X-ray bursts with improved nuclear physics

TL;DR: In this paper, the authors present multizone models of Type I X-ray bursts that use an adaptive nuclear reaction network of unprecedented size, up to 1300 isotopes, for energy generation and include the most recent measurements and estimates of critical nuclear physics.
Journal ArticleDOI

Models for Type I X-Ray Bursts with Improved Nuclear Physics

TL;DR: In this paper, multi-zone models of Type I X-ray bursts are presented that use an adaptive nuclear reaction network of unprecedented size, up to 1300 isotopes, and sequences of up to 15 bursts are followed for two choices of accretion rate and metallicity.
Journal ArticleDOI

The Production of 44Ti and 60Co in Supernovae

TL;DR: In this article, the production of the radioactive isotopes {sup 44}Ti and {sup 60}Co in all types of supernovae is examined and compared to observational constraints including Galactic {gamma}-ray surveys, measurements of the diffuse 511 keV radiation, the late-time light curve of SN 1987A, and isotopic anomalies found in silicon carbide grains in meteorites.
Journal ArticleDOI

26Al and 60Fe from Supernova Explosions

TL;DR: In this paper, the current abundances and spatial distributions of two key gamma-ray radioactivities, {sup 26}Al and {sup 60}Fe, are determined using recently calculated yields for Type II supernovae, along with models for chemical evolution and distribution of mass in the interstellar medium.
