Strong Coupling of Hydrodynamics and Reactions in Nuclear Statistical Equilibrium for Modeling Convection in Massive Stars

open access: yesThe Astrophysical Journal
We build on the simplified spectral deferred corrections (SDC) coupling of hydrodynamics and reactions to handle the case of nuclear statistical equilibrium (NSE) and electron/positron captures/decays in the cores of massive stars.

Consistency of cosmic-ray source abudances with explosive nucleosynthesis

open access: yes, 1973
A model was examined in which the cosmic ray abundances of elements from C to Fe are consistent with explosive nucleosynthesis. The observed abundance of cosmic rays near the earth, cosmic ray source abundance, and solar system abundance are discussed ...

Explosive hydrogen burning

open access: yes, 1992
Under astrophysical conditions of extreme temperature and density, nuclear reactions can occur with rates that are comparable to a dynamical free-fall time, i.e. on the order of seconds.

Sm-147(n,alpha) cross section measurements from 3 eV to 500 keV : implications for explosive nucleosynthesis reaction rates

open access: yes, 2000
We have measured the Sm-147(n, alpha) cross section from 3 eV to 500 keV. These data were used to test nuclear statistical models which must be relied on to calculate the rates for as yet unmeasurable reactions occurring in explosive nucleosynthesis ...

Kilonova Emissions from Neutron Star Merger Remnants: Implications for the Nuclear Equation of State

open access: yesThe Astrophysical Journal
Multimessenger observations of binary neutron star mergers can provide valuable information on the nuclear equation of state (EOS). Here, we investigate the extent to which electromagnetic observations of the associated kilonovae allow us to place ...

Collapsars as Sites of r-process Nucleosynthesis: Systematic Photometric Near-infrared Follow-up of Type Ic-BL Supernovae

open access: yesThe Astrophysical Journal
One of the open questions following the discovery of GW170817 is whether neutron star (NS) mergers are the only astrophysical sites capable of producing r -process elements.
