Nuclear astrophysics with neutrons [PDF]

open access: bronzeJournal 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 ...

Experimental nuclear astrophysics in Italy

open access: yesRivista Del Nuovo Cimento, 2019
Nuclear astrophysics, the union of nuclear physics and astronomy, went through an impressive expansion during the last twenty years. This could be achieved thanks to milestone improvements in astronomical observations, cross section measurements, powerful computer simulations and much refined stellar models.

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.
