Gravitational waves from binary compact star mergers in the context of strange matter
EPJ Web of Conferences, 2018 In this article we will focus on the appearance of the hadron-quark phase transition and the formation of strange matter in the interior region of the hypermassive neutron star and its conjunction with the spectral properties of the emitted gravitational

The quark strange star in the enlarged Nambu-Jona-Lasinio model [PDF]
, 2002 The strange quark star is investigated within the enlarged SU(3) Nambu-Jona-Lasinio (NJL). The stable quark star exists till maximal configutation with rho_m=3.1, 10^15, g/cm^3 with M_m=1.61, M_Sun and R_m=8.74, km is reached.

Electrically charged strange quark stars [PDF]
Physical Review D, 2009 The possible existence of compact stars made of absolutely stable strange quark matter--referred to as strange stars--was pointed out by E. Witten almost a quarter of a century ago. One of the most amazing features of such objects concerns the possible existence of ultra-strong electric fields on their surfaces, which, for ordinary strange matter, is ...

ANALYTICAL MODELS FOR QUARK STARS [PDF]
International Journal of Modern Physics D, 2007 We find two new classes of exact solutions to the Einstein–Maxwell system of equations. The matter content satisfies a linear equation of state consistent with quark matter; a particular form of one of the gravitational potentials is specified to generate solutions.

European Physical Journal C: Particles and Fields, 2020 The phase diagram of dense quark matter with chiral imbalance is considered with the conditions of electric neutrality and $$\beta $$ β -equilibrium. It has been shown recently that chiral imbalance can generate charged pion condensation (PC) in dense ...

Quark phases in neutron stars and a "third family" of compact stars as a signature for phase transitions [PDF]
, 2000 The appearance of quark phases in the dense interior of neutron stars provides one possibility to soften the equation of state (EOS) of neutron star matter at high densities.

RIGIDLY ROTATING STRANGE QUARK STARS
International Journal of Modern Physics D, 2005 In this article, we study rotating strange quark stars in the context of general relativity. For this purpose we consider perfect fluid model composed of strange quark matter with electromagnetic field in the Gödel Universe which has rigid rotation. We solve Einstein's field equations by using equation of state for strange quark matter.
