Production of Heavy α-Elements and 44Ti in Cas A: Comparison to Abundances from 1D Core-collapse Supernova Models and Evidence for Carbon–Oxygen Shell Mergers

The Astrophysical Journal Letters
The merger between the carbon (C) and oxygen (O) shells hours to days before the collapse of a massive star significantly changes its nucleosynthesis, which is reflected in the elemental ratios observed in supernova remnants (SNRs).

Exploring the Neutrino Mass Hierarchy from Isotopic Ratios of Supernova Nucleosynthesis Products in Presolar Grains

The Astrophysical Journal
We study the nucleosynthesis in a core-collapse supernova (CCSN) model including newly calculated neutrino-induced reaction rates with both collective and Mikheyev–Smirnov–Wolfenstein neutrino flavor oscillations considered.

Indirect nuclear physics techniques for studying nova nucleosynthesis

, 2009
Classical novae are a site of explosive nucleosynthesis where hydrogen rich material from a companion giant star accretes onto the surface of a white warf. Critical to our understanding of nova explosions are proton-capture reaction rates involved in the

Nuclear aspects of stellar and explosive nucleosynthesis

, 2001
The majority of nuclear reactions in astrophysics involve unstable nuclei which are not yet fully accessible by experiments. Therefore, there is high demand for reliable predictions of cross sections and reaction rates by theoretical means.

Galactic Chemical Evolution of Short-lived Radioactive Isotopes Produced by Explosive Nucleosynthesis: 60Fe and 53Mn

The Astronomical Journal
Several short-lived radionuclides (SLRs) are know to have existed in the early solar system (ESS). These species, which typically decay with half-lives of the order of a few million years, can be used to probe the timescales of events preceding the birth

Az elemek nukleoszintézise lassú és robbanásos folyamatokban = Stellar and explosive nucleosynthesis

, 2008
A pályázat során a nukleoszintézis magfizikai aspektusait tanulmányoztuk. A Napban lejátszódó rendkívül kis valószínűségű atommagreakciókat egy földalatti laboratóriumba telepített részecskegyorsító segítségével mértük meg.
