Neutrino oscillations at high densities: cosmological and astrophysical aspects
, 2011 This doctoral thesis treats the effects of neutrino oscillations in the early universe and supernovae. The main probe for the context of the early universe is big bang nucleosynthesis (BBN).

Heavy Elements and Electromagnetic Transients from Neutron Star Mergers
Annalen der Physik, Volume 536, Issue 2, February 2024.Astro‐(physics) has made major leaps forward through the combined information provided by both gravitational waves and electromagnetic emission from the first detected neutron star merger event. This review provides an up‐to‐date overview of today's understanding of neutron star mergers and their electromagnetic emission and it discusses possible ...

Galactic cosmic rays and nucleosynthesis
, 2009 International audienceThe nucleosynthesis of the light elements Li, Be and B by galactic cosmic rays is presented. Observations of cosmic rays and the nuclear reactions responsible for Li, Be and B nucleosynthesis are described, followed by some words on

, 2014 The origin of the extreme hydrogen deficiency observed in the R Coronae Borealis (RCrB) stars remains poorly understood. A likely mechanism for producing this deficiency is one whereby the original hydrogen envelope of the star is engulfed and ...

Nucleosynthesis in Early Neutrino Driven Winds [PDF]
, 2008 Two recent issues related to nucleosynthesis in early proton-rich neutrino winds are investigated. In the first part we investigate the effect of nuclear physics uncertainties on the synthesis of {sup 92}Mo and {sup 94}Mo.

Nuclear reactions for nucleosynthesis beyond Fe [PDF]
, 2015 Many more nuclear transitions have to be known in the determination of stellar reactivities for trans-iron nucleosynthesis than for reactions of light nuclei. This requires different theoretical and experimental approaches.

Chemical evolution and kilonova implications of post-merger accretion disk winds
Astronomy & AstrophysicsContext. 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.

Nucleosynthesis Predictions and High-Precision Deuterium Measurements
Universe, 2017 Two new high-precision measurements of the deuterium abundance from absorbers along the line of sight to the quasar PKS1937–1009 were presented. The absorbers have lower neutral hydrogen column densities (N(HI) ≈ 18 cm − 2 ) than for previous ...

New Results on Nucleosynthesis in Massive Stars; Nuclear Data Needs for
, 2001 Introduction Second only in scientific interest to the origin of the universe itself is the origin of the chemical elements therein. The near term goal of nuclear origins, or nucleosynthesis, seeks to develop a complete understanding of the origin of ...
