Confronting strange stars with compact-star observations and new physics

S Yang, C Pi, X Zheng, F Weber - Universe, 2023 - mdpi.com
Strange stars ought to exist in the universe according to the strange quark matter hypothesis,
which states that matter made of roughly equal numbers of up, down, and strange quarks …

Thermodynamics, strange quark matter, and strange stars

GX Peng, HC Chiang, BS Zou, PZ Ning, SJ Luo - Physical Review C, 2000 - APS
Upon application of both the general ensemble theory and basic thermodynamical

Three-dimensional hydrodynamic simulations<? format?> of the combustion of a neutron star into a quark star

M Herzog, FK Röpke - Physical Review D—Particles, Fields, Gravitation, and …, 2011 - APS
We present three-dimensional numerical simulations of turbulent combustion converting a
neutron star into a quark star. Hadronic matter, described by a microphysical finite …

Mass formulas and thermodynamic treatment in the mass-density-dependent model of strange quark matter

GX Peng, HC Chiang, JJ Yang, L Li, B Liu - Physical Review C, 1999 - APS
The previous treatments for strange quark matter in the quark mass-density-dependent
model have unreasonable vacuum limits. We provide a method to obtain the quark mass …

Deconfinement phase transition in hybrid neutron stars from the Brueckner theory with three-body forces and a quark model with chiral mass scaling

GX Peng, A Li, U Lombardo - Physical Review C—Nuclear Physics, 2008 - APS
We study the properties of strange quark matter in equilibrium with normal nuclear matter.
Instead of using the conventional bag model in quark sector, we achieve the confinement by …

Thermodynamic consistency, quark mass scaling, and properties of strange matter

CJ Xia, GX Peng, SW Chen, ZY Lu, JF Xu - Physical Review D, 2014 - APS

XJ Wen, XH Zhong, GX Peng, PN Shen, PZ Ning - Physical Review C …, 2005 - APS
Thermodynamic formulas for investigating systems with density-and/or temperature-
dependent particle masses are generally derived from the fundamental derivation equality of …

Stability windows for proto-quark stars
