International Journal of Modern Physics APulsar-like objects are extremely compact, with an average density that exceeds nuclear saturation density, where the fundamental strong interaction plays an essential role, particularly in the low-energy regime. The internal structures and properties of those objects are profoundly connected to phenomena such as supernova explosions, gamma-ray bursts (

Quark Matter May Not Be Strange [PDF]
Physical Review Letters, 2018 If quark matter is energetically favored over nuclear matter at zero temperature and pressure then it has long been expected to take the form of strange quark matter (SQM), with comparable amounts of $u$, $d$, $s$ quarks. The possibility of quark matter with only $u$, $d$ quarks ($ud$QM) is usually dismissed because of the observed stability of ...

Phase transition toward strange matter [PDF]
Physical Review C, 2012 The phase diagram of a system constituted of neutrons and $ $-hyperons in thermal equilibrium is evaluated in the mean-field approximation. It is shown that this simple system exhibits a complex phase diagram with first and second order phase transitions.

Physical Review Letters, 1993 We have studied the composition, stability, and production mechanisms of strange hadronic matter. By applying the RMF model to systems of nucleons, Λ’s, Σ’s, and Ξ’s, stable systems with hyperon lifetimes and charge to mass ratio close to zero are obtained. In this extended model, purely hyperonic matter consisting of lambda’s and cascades is predicted.

Strange stars within bosonic and fermionic admixed dark matter [PDF]
Journal of Cosmology and Astroparticle Physics, 2023 In this work, we study dark matter (DM) admixed strange quark stars exploring the different possibilities about the nature of the DM and their effects on the macroscopic properties of strange stars, such as maximum masses, radii, as well the ...

Strange magnetars admixed with fermionic dark matter [PDF]
Journal of Cosmology and Astroparticle Physics, 2022 We discuss strange stars admixed with fermionic dark matter in the presence of a strong magnetic field using the two-fluid Tolman-Oppenheimer-Volkov equations.

Compact star merger events with stars composed of interacting strange quark matter [PDF]
Monthly notices of the Royal Astronomical Society, 2022 We investigate the properties of stars participating in double compact star merger events considering interacting model of stable strange quark matter.

Vector dark boson mediated feeble interaction between fermionic dark matter and strange quark matter in quark stars [PDF]
, 2022 We study the structural properties like the gravitational mass, radius and tidal deformability of dark matter (DM) admixed strange quark stars (SQSs).

Hybrid stars with hyperons and strange quark matter [PDF]
PROCEEDINGS OF THE 14TH ASIA-PACIFIC PHYSICS CONFERENCE, 2020 We consider the possibility of having hybrid stars with a phase transition from hadrons into strange matter at the core of a neutron star in b equilibrium. For the hadron phase equation of state (EoS) the quark-meson coupling model is used, while the MIT
