Magnetars as highly magnetized quark stars: An analytical treatment
(IOP Publishing, 2011-06)
We present an analytical model of a magnetar as a high-density magnetized quark bag. The effect of strong magnetic fields (B > 5 × 10^16 G) in the equation of state is considered. An analytic expression for the mass-radius ...
Hybrid stars with sequential phase transitions: the emergence of the g2 mode
(IOP Publishing, 2021-02)
Neutron stars are the densest objects in the Universe, with M=1.4 M_Sun and R=12 km, and the equation of state associated to their internal composition is still unknown. The extreme conditions to which matter is subjected ...
Effects of Hadron-Quark Phase Transitions in Hybrid Stars within the NJL Model
(Multidisciplinary Digital Publishing Institute, 2019-03-22)
We study local and non-local Polyakov Nambu-Jona-Lasinio models and analyze their respective phase transition diagram. We construct hybrid stars using the zero temperature limit of the local and non-local versions of ...
First-order phase transition from hypernuclear matter to deconfined quark matter obeying new constraints from compact star observations
(American Physical Society, 2020-02)
We reconsider the problem of the hyperon puzzle and its suggested solution by quark deconfinement within the two-phase approach to hybrid compact stars with recently obtained hadronic and quark matter equations of state. ...
