Neural Network Construction of the Equation of State from Relativistic ab initio Calculations

open access: yesThe Astrophysical Journal
Constraining the nuclear matter equation of state (EOS) beyond saturation density is crucial in nuclear physics and astrophysics. While the relativistic Brueckner–Hartree–Fock (RBHF) theory, an ab initio, nonperturbative nuclear many-body theory starting

Observations and Simulation of Thermospheric Composition Changes During the 14 October 2023 Solar Eclipse

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract This study presents a full‐period imaging of the thermospheric composition response to the 14 October 2023 annular solar eclipse, combining GOLD (Global‐scale Observations of the Limb and Disk) far‐ultraviolet observations with solar‐irradiance‐driven WACCM‐X (Whole Atmosphere Community Climate Model with thermosphere–ionosphere extension ...

Degenerate Neutron Capture Rates in the Threshold of Neutron Star–Black Hole Mergers

open access: yesThe Astrophysical Journal
We first show that the rate of energy generation due to neutron capture rates can be important in neutron star–black hole mergers (NS–BH mergers) by considering neutron degeneracy.

Underground Nuclear Astrophysics at LUNA

open access: yesActa Physica Polonica B, 2018
Since 1991, LUNA (Laboratory for Underground Nuclear Astrophysics) has played a leading role in the direct measurement of nuclear cross sections relevant to astrophysics, producing several pioneering results. Thanks to the shielding provided by the Gran Sasso mountain, LUNA enables measuring very small cross sections of the nuclear reactions involved ...
