Low-energy nuclear physics and global neutron star properties

Autor: Brett V. Carlson, Mariana Dutra, Odilon Lourenço, Jérôme Margueron

Publikováno v: HAL

We address the question of the role of low-energy nuclear physics data in constraining neutron star global properties, e.g., masses, radii, angular momentum, and tidal deformability, in the absence of a phase transition in dense matter. To do so, we

We review how the "cusp" predicted in the nuclear symmetry energy generated by a topology change at density $n_{1/2}\gsim 2 n_0$ can have a surprising consequence, so far unrecognized in nuclear physics and astrophysics communities, on the structure

Cusp in the Symmetry Energy, PREX-II And Pseudo-Conformal Sound Speed in Neutron Stars

Autor: Lee, Hyun Kyu, Ma, Yong-Liang, Paeng, Won-Gi, Rho, Mannque

The recent announcement of the PREX-II measurement of the neutron skin of $^{208}$Pb that suggests a stiff symmetry energy near nuclear matter density $n_0$ and its impact on the EoS of massive compact stars raise the issue as to whether the widely a

The nuclear symmetry energy is a key quantity in nuclear (astro)physics. It describes the isospin dependence of the nuclear equation of state (EOS), which is commonly assumed to be almost quadratic. In this work, we confront this standard quadratic e
