Stellar properties and nuclear matter constraints

Properties of stellar matter in supernova explosions and nuclear multifragmentation

During the collapse of massive stars, and the supernova type-II explosions, stellar matter reaches densities and temperatures which are similar to the ones obtained in intermediate-energy nucleus-nucleus collisions. The nuclear multifragmentation reactions can be used for determination of properties of nuclear matter at subnuclear densities, in the region of the nuclear liquid-gas phase transit...

Thermodynamical properties of stellar matter

Starting from the Helmholtz free energy we calculate analytically first-and second-order derivatives, as internal energy and specific heats, for the ideal system and the exchange and correlation interactions covering a broad range of degeneracy and relativity. The complex physics of Coulomb interactions is expressed by Padé Approximants, which reflect the actual state of our knowledge with high...

Bulk Nuclear Properties and Nuclear Matter

The universe contains a remarkably wide variety of atomic nuclei, with mass numbers A (the sum of the numbers of proton Z and the neutron N) up to 250. While there are many interesting properties details that differentiate these nuclei from each other, there is also a powerful set of systematic trends and general properties that provide an important and useful framework for understanding the ba...

Skyrme interaction and nuclear matter constraints

This paper presents a detailed assessment of the ability of the 240 Skyrme interaction parameter sets in the literature to satisfy a series of criteria derived from macroscopic properties of nuclear matter in the vicinity of nuclear saturation density at zero temperature and their density dependence, derived by the liquid-drop model, in experiments with giant resonances and heavy-ion collisions...
