Strangeness in stellar matter [PDF]
Acta Physica Hungarica A) Heavy Ion Physics, 1996 A protoneutron star is formed immediately after the gravitational collapse of the core of a massive star. At birth, the hot and high density matter in such a star contains a large number of neutrinos trapped during collapse. Trapped neutrinos generally inhibit the presence of exotic matter -- hyperons, a kaon condensate, or quarks.

Confronting Strange Stars with Compact-Star Observations and New Physics
Universe, 2023 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 could be the true ground state of baryonic matter rather than ordinary ...

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.

Bulk strong matter: the trinity
Advances in Physics: X, 2023 Our world is wonderful because of the normal but negligibly small baryonic part (i.e. atoms) although unknown dark matter and dark energy dominate the Universe.

Sensitivity of KM3NeT/ARCA to a flux of nuclearites [PDF]
EPJ Web of Conferences, 2023 Over the past decades, theories have predicted the existence of heavy compact objects containing an extremely dense form of exotic matter named Strange Quark Matter (SQM).

Universe, 2023 In 1995, Glendenning, Kettner and Weber postulated the existence of a new class of compact stars resembling white dwarfs but containing a small strange quark-matter core surrounded by hadronic layers attaining much higher densities than those found in ...

Strangeness and charm in nuclear matter [PDF]
Nuclear Physics A, 2013 The properties of strange ($K$, $\bar K$ and $\bar K^*$) and open-charm ($D$, $\bar D$ and $D^*$) mesons in dense matter are studied using a unitary approach in coupled channels for meson-baryon scattering. In the strangeness sector, the interaction with nucleons always comes through vector-meson exchange, which is evaluated by chiral and hidden gauge ...

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 ...

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.
