Neutrino treatment in multidimensional astrophysical simulations : a new spectral scheme [PDF]
, 2014 Neutrinos play a central role in modern physics and astrophysics. Their extremely weak interaction rate with baryons and other leptons makes their detection on the Earth difficult and challenging.

, 2022 Cosmic nucleosynthesis had been one of INTEGRAL’s major science targets. The SPI spectrometer delivered important measurements, both from targets of opportunity in the form of stellar explosions and their shortlived radionuclides, and from cumulative emission of long-lived radioactive isotopes. We review the lessons learned on explosive nucleosynthesis

Neutrino radiation hydrodynamics in hot and dense nuclear matter and the role of microphysics in simulations of massive stars [PDF]
, 2010 The main results of my doctoral studies were obtained from core collapse simulations of massive stars using a numerical model based on radiation hydrodynamics and three-flavour Boltzmann neutrino transport in spherical symmetry.

Fusion reactions induced by radioactive beams: the 18F(p,α)15O case
EPJ Web of Conferences, 2017 Gamma ray astronomy has made big strides in the last decades paving the way to a better understanding of explosive nucleosynthesis. In particular, crucial information on novae nucleosynthesis is linked to the abundance of the 18F isotope, which might be ...

Nucleosynthesis in explosive environments : neutron star mergers and core-collapse supernovae [PDF]
, 2016 Several nucleosynthesis processes are responsible for the production of the chemical elements in the universe. Explosive ejecta in core-collapse supernovae typically produce intermediate-mass elements up to the iron-group nuclei, although the exact ...

Comparison of the Core-collapse Evolution of Two Nearly Equal-mass Progenitors
The Astrophysical Journal, 2023 We compare the core-collapse evolution of a pair of 15.8 M _☉ stars with significantly different internal structures, a consequence of the bimodal variability exhibited by massive stars during their late evolutionary stages.

Examining Neutrino–Matter Interactions in the Cassiopeia A Supernova
The Astrophysical Journal, 2023 Neutrino interactions with stellar material are widely believed to be fundamental to the explosion of massive stars. However, this important process has remained difficult to confirm observationally.

Meteoritics &Planetary Science, Volume 54, Issue 5, Page 1092-1114, May 2019., 2019 Abstract Solar abundances are important to planetary science since the prevalent model assumes that the composition of the solar photosphere is that of the solar nebula from which planetary materials formed. Thus, solar abundances are a baseline for planetary science.

What do (and don't) we understand about explosive nucleosynthesis? [PDF]
, 2011 Isotopic abundances reflect both nuclear structure and environmental history. Observations are providing new evidence that is helping us to understand astrophysical phenomena, the chemical history of the Galaxy, and the origins of the diverse isotopic ...
