Nucleosynthesis and Gamma-Ray Line Spectroscopy with INTEGRAL

, 2011
Cosmic nucleosynthesis co-produces unstable isotopes, which emit characteristic gamma-ray emission lines upon their radioactive decay that can be measured with SPI on INTEGRAL.

Nucleosynthesis in multi-dimensional SNIa explosions

, 2004
We present the results of nucleosynthesis calculations based on multidimensional (2D and 3D) hydrodynamical simulations of the thermonuclear burning phase in SNIa.

Baryon inhomogeneity generation via cosmic strings at QCD scale and its effects on nucleosynthesis

, 2002
We have earlier shown that cosmic strings moving through the plasma at the time of a first order quark-hadron transition in the early universe can generate large scale baryon inhomogeneities.

The Impact of Recent LUNA Measurements of NeNa Reactions on ²⁶Al Stellar Nucleosynthesis

Universe
Recent measurements performed by the LUNA(Laboratory for Underground Nuclear Astrophysics) collaboration between 2019 and 2024 have provided the most precise direct determinations to date of several key reaction rates in the NeNa cycle, specifically the ...

Chemical evolution and kilonova implications of post-merger accretion disk winds

Astronomy & Astrophysics
Context. Several gamma-ray bursts (GRBs) have recently been associated with kilonova emission. We study the mechanisms that account for this effect by means of the radioactive decay of elements synthesized in accretion disk winds. Aims.
