Breakup of loosely bound nuclei as indirect method in nuclear astrophysics: 8B, 9C, 23Al [PDF]

, 2005
We discuss the use of one-nucleon breakup reactions of loosely bound nuclei at intermediate energies as an indirect method in nuclear astrophysics. These are peripheral processes, therefore we can extract asymptotic normalization coefficients (ANC) from ...

Nuclear astrophysics and underground accelerators

Physics of the Dark Universe, 2014
AbstractAccurate knowledge of thermonuclear reaction rates is a key issue in nuclear astrophysics since it is important for understanding the energy generation, neutrino production and the synthesis of the elements in stars. Cross-section measurements are mainly hampered by the very low counting rate and cosmic background.

Nuclear astrophysics with neutrons [PDF]

Journal of Instrumentation, 2012
Neutrons play a crucial role in astrophysics during the heavy element nucleosynthesis. The largest fraction of isotopes heavier than iron is produced by neutron capture processes on short (r process) and long timescales (s process). During the ``slow neutron capture process'' (s process) heavier elements are produced by successive captures of in-situ ...

Underground nuclear astrophysics studies with CASPAR

EPJ Web of Conferences, 2016
The drive of low-energy nuclear astrophysics laboratories is to study the reactions of importance to stellar burning processes and elemental production through stellar nucleosynthesis, over the energy range of astrophysical interest.

Horizons: nuclear astrophysics in the 2020s and beyond [PDF]

Journal of Physics G: Nuclear and Particle Physics, 2022
Nuclear astrophysics is a field at the intersection of nuclear physics and astrophysics, which seeks to understand the nuclear engines of astronomical objects and the origin of the chemical elements.

pynucastro: A Python Library for Nuclear Astrophysics [PDF]

Astrophysical Journal, 2022
We describe pynucastro 2.0, an open-source library for interactively creating and exploring astrophysical nuclear reaction networks. We demonstrate new methods for approximating rates and use detailed balance to create reverse rates, show how to build ...

Transfer Reactions As a Tool in Nuclear Astrophysics [PDF]

Frontiers of Physics, 2021
Nuclear reaction rates are one of the most important ingredients in describing how stars evolve. The study of the nuclear reactions involved in different astrophysical sites is thus mandatory to address most questions in nuclear astrophysics.

A New Mass Model for Nuclear Astrophysics: Crossing 200 keV Accuracy [PDF]

Universe, 2021
By using a machine learning algorithm, we present an improved nuclear mass table with a root mean square deviation of less than 200 keV. The model is equipped with statistical error bars in order to compare with available experimental data.

An updated nuclear-physics and multi-messenger astrophysics framework for binary neutron star mergers [PDF]

Nature Communications, 2022
The multi-messenger detection of the gravitational-wave signal GW170817, the corresponding kilonova AT2017gfo and the short gamma-ray burst GRB170817A, as well as the observed afterglow has delivered a scientific breakthrough.
