Reconciling nuclear and astrophysical constraints [PDF]

open access: yesPhysical Review C, 2015
In view of new constraints put forth by recent observations and measurements in the realm of astrophysics and nuclear physics, we update the non-linear realization of the sigma model as to reflect such constraints. By doing this, we obtain new equations of state that may be used to describe neutron stars.

Anomalous‐Energy Runaway Electrons Originating in Fast Ionisation Wave During Pulsed Gas Breakdown

open access: yesHigh Voltage, EarlyView.
ABSTRACT Anomalous‐energy runaway electrons (RAEs), whose energy exceeds the maximum potential difference across the discharge gap, are widely observed in various plasma phenomena. This study investigates the origination of anomalous‐energy RAEs in fast ionisation waves (FIWs) formed during pulsed gas breakdown.

Nuclear Astrophysics Deep Underground [PDF]

open access: yesInternational Journal of Modern Physics: Conference Series, 2018
Cross sections of nuclear reactions relevant for astrophysics are crucial ingredients to understand the energy generation inside stars and the synthesis of the elements. At astrophysical energies, nuclear cross sections are often too small to be measured in laboratories on the Earth surface, where the signal would be overwhelmed by the cosmic-ray ...

Reaction models in nuclear astrophysics

open access: yesEPJ Web of Conferences, 2016
We present different reaction models commonly used in nuclear astrophysics, in particular for the nucleosynthesis of light elements. Pioneering works were performed within the potential model, where the internal structure of the colliding nuclei is ...

Statistical Spectroscopy for Neutron-rich sd-Shell Nuclei

open access: yes, 2012
Statistical spectroscopic results using the spectral distribution theory are obtained for the structure of neutron-rich light nuclei going towards the drip line and compared to experimental values available.

Noble gases and nitrogen in material from asteroid Bennu

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract We report the elemental and isotopic abundances of all stable noble gases (helium, neon, argon, krypton, and xenon) in eight particles from asteroid Bennu returned by NASA's OSIRIS‐REx mission. We also report nitrogen abundances and isotopic ratios that were analyzed alongside neon and argon in four additional Bennu particles.

Nuclear Astrophysics With Gamma-Beams

open access: yesJournal of Physics: Conference Series, 2018
Gamma-Beams now available at the HIγS facility of the TUNL at Duke University and soon to be available at the Extreme Light Infrastructure - Nuclear Physics (ELI-NP) in Magurele, near Bucharest, Romania, present scientific opportunities for progress in ...

Transfer reactions for nuclear astrophysics

open access: yesEPJ Web of Conferences, 2018
Direct measurements of cross sections at stellar energies are very challenging - if at all possible. This is essentially due to the very low cross-sections of the reactions of interest (especially when it involves charged particles), and/or to the ...

Non-explosive hydrogen and helium burnings: Abundance predictions from the NACRE reaction rate compilation [PDF]

open access: yes, 1999
The abundances of the isotopes of the elements from C to Al produced by the non-explosive CNO, NeNa and MgAl modes of hydrogen burning, as well as by helium burning, are calculated with the thermonuclear rates recommended by the European compilation of ...
