Finite-Size Effects on the Critical End Point of Magnetized Quark Matter in the Nonlocal PNJL Model
G. Lugones, S. A. Ferraris, A. G. Grunfeld
We investigate finite-size effects in the - phase diagram of magnetized quark matter within the framework of a nonlocal extension of the Polyakov--Nambu--Jona-Lasinio (PNJL)…
The sharpness of the quark-hadron transition and the properties of hybrid stars
M. B. Albino, R. Fariello, G. Lugones +1
We investigate the effects of the sharpness of the phase transition between hadronic matter and quark matter on various properties of neutron stars. We construct hybrid equations o…
Dark interactions in neutron star interiors: the interplay of baryons, dark matter, and dark energy
L. F. Araujo, G. Lugones, J. A. S. Lima
The impact of energy exchange among the relevant fluid components: baryonic matter, fermionic dark matter (DM), and dark energy (DE) on the internal structure of neutron stars is i…
Neutron star stability beyond the mass peak: assessing the role of out-of-equilibrium perturbations
Martin O. Canullan-Pascual, German Lugones, Milva G. Orsaria +1
We investigate the radial stability of neutron stars under conditions where their composition may or may not remain in chemical equilibrium during oscillations. Using different equ…
