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…

Could a slow stable hybrid star explain the central compact object in HESS~J1731-347?

Mauro Mariani, Ignacio F. Ranea-Sandoval, Germán Lugones +1

We explore an alternative explanation for the low-mass ultra-compact star in the supernova remnant HESS~J1731-347 using a model-agnostic approach to construct hybrid equations of s…

Impact of dark energy on the structure of neutron stars: The vacuum case

L. F. Araujo, J. A. S. Lima, G. Lugones

The potential role of a cosmic vacuum dark component in the properties of neutron stars is investigated. It is assumed that the static, spherically symmetric distribution of matter…
