Neutrinos and nucleosynthesis of elements

Neutrinos are known to play important roles in many astrophysical scenarios from the early period of the big bang to current stellar evolution being a unique messenger of the fusion reactions occurring in the center of our sun.

Explosive nucleosynthesis at strong magnetic field

, 2014
The effect of a strong magnetic field on the synthesis of chemical elements is considered at conditions of nuclear statistical equilibrium. The possibility to employ the produced radionuclides to probe the transient ultra-magnetized astrophysical plasma ...

Type Ia Supernovae Can Arise from the Detonations of Both Stars in a Double Degenerate Binary

The Astrophysical Journal
The precise origin of Type Ia supernovae (SNe Ia) is unknown despite their value to numerous areas in astronomy. While it is a long-standing consensus that they arise from the explosion of a carbon/oxygen white dwarf, the exact progenitor configurations ...

Explosive nucleosynthesis in core-collapse supernovae and the titanium problem [PDF]

Based on a new mechanism to drive spherically symmetric core-collapse supernovae, PUSH, we perform full network nucleosynthesis calculations for different progenitors.

The role of neutrinos in explosive nucleosynthesis

, 2006
We present a new primary nucleosynthesis process, the # p-process, occurring in supernovae (and possibly gamma-ray bursts) when strong neutrino fluxes create proton-rich ejecta.

A Photoionization Model for the Infrared Coronal Line Emission in the Classical Nova V1716 Scorpii

The Astrophysical Journal
A near-infrared spectrum of nova V1716 Scorpii (PNV J17224490-4137160), a recent bright ( ${V}_{\max }=7.3$ mag), Fermi-LAT detected γ -ray source, was modeled using the photoionization code CLOUDY.

Reconciling the Tension between Light-curve Modeling of Type II Supernovae and Neutrino-driven Core-collapse Supernovae Models with Late-phase Spectroscopy

The Astrophysical Journal
Type II supernovae (SNe II) are the most frequently observed outcome of core-collapse explosions and provide a valuable window into the physical mechanisms governing the deaths of massive stars. However, estimates of explosion properties based on optical

Explosive nucleosynthesis close to the drip lines

, 1998
We give an overview of explosive burning and the role which neutron and/or proton separation energies play. We focus then on the rapid neutron capture process (r-process) which encounters unstable nuclei with neutron separation energies in the range 1-4 ...
