Medium effects in strange quark matter and strange stars [PDF]
Nucl.Phys. A616 (1997) 659-679, 1996 We investigate the properties of strange quark matter at zero temperature including medium effects. The quarks are considered as quasiparticles which acquire an effective mass generated by the interaction with the other quarks of the dense system. The effective quark masses are derived from the zero momentum limit of the dispersion relations following ...

Strange-quark-matter stars [PDF]
, 1989 We investigate the implications of rapid rotation corresponding to the frequency of the new pulsar reported in the supernovae remnant SN1987A. It places very stringent conditions on the equation of state if the star is assumed to be bound by gravity alone. We find that the central energy density of the star must be greater than 13 times that of nuclear

Electrically charged strange quark stars
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.

Strange quark matter and compact stars [PDF]
Progress in Particle and Nuclear Physics, 2005 Astrophysicists distinguish between three different types of compact stars. These are white dwarfs, neutron stars, and black holes. The former contain matter in one of the densest forms found in the Universe which, together with the unprecedented progress in observational astronomy, make such stars superb astrophysical laboratories for a broad range of

Gravitational Waves from Strange Star Core–Crust Oscillation
Universe, 2022 According to the strange quark matter hypothesis, pulsars may actually be strange stars composed of self-bound strange quark matter. The normal matter crust of a strange star, unlike that of a normal neutron star, is supported by a strong electric field.

The strange-quark distribution [PDF]
Zeitschrift für Physik C: Particles and Fields, 1996 We discuss the latest CCFR determination of the strange sea density of the proton. We comment on the differences with a previous, leading--order, result and point out the relevance of quark mass effects and current non--conservation effects. By taking them into account it is possible to solve the residual discrepancy with another determination of the ...

Tidal Deformability of Strange Quark Planets and Strange Dwarfs [PDF]
Phys. Rev. D 104, 123028 (2021), 2021 Strange quark matter, which is composed of u, d, and s quarks, could be the true ground of matter. According to this hypothesis, compact stars may actually be strange quark stars, and there may even be stable strange quark dwarfs and strange quark planets.

Is distinct location evidence of distinct objects? Multilocation and the problem of parsimony
Analytic Philosophy, EarlyView., 2023 Abstract For an object to be multilocated is for it to wholly occupy disjoint spatial regions simultaneously. If multilocation is possible, it is possible that a multilocated particle is wholly located at 1080 distinct locations, such that it constitutes a particle‐for‐particle duplicate of the actual universe.
