New mass limit of a strange star admitting a colour flavor locked equation of state

European Physical Journal C: Particles and Fields, 2023
A class of strange stars is analysed in the present article in hydrostatic equilibrium, whose state is defined by a CFL phase equation of state. We have compared our results with those obtained from the MIT equation of state for strange quark matter ...

Hyperon Physics with PANDA at FAIR [PDF]

EPJ Web of Conferences, 2020
Hyperons provide new angles on two of the most challenging problems in contemporary physics: a coherent and quantitative description of the strong interaction, and the matter-antimatter asymmetry of the Universe.

Electric fields at the quark surface of strange stars in the color-flavor locked phase [PDF]

, 2004
It is shown that extremely strong electric fields may be generated at the surface of strange quark matter in the color-flavor locked phase because of the surface effects. Some properties of strange stars made of this matter are briefly discussed.Comment:

Torsional oscillations of strange stars

EPJ Web of Conferences, 2014
Strange stars are one of the hypothetical compact stellar objects that can be formed after a supernova explosion. The existence of these objects relies on the absolute stability of strange collapsed quark matter with respect to standard nuclear matter ...

Is SAX J1808.4-3658 a Strange Star ? [PDF]

, 1999
One of the most important questions in the study of compact objects is the nature of pulsars, including whether they are composed of $\beta$-stable nuclear matter or strange quark matter. Observations of the newly discovered millisecond X-ray pulsar \sax

Charged strange stellar model describing by Tolman V metric

Results in Physics, 2021
This paper deals with the existence of a compact stellar object, precisely strange (quark) star, in the framework of Einstein’s General Theory of Relativity with Tolman V metric potential, which is one of the simplest forms of potential among his ...

Boiling of strange-quark matter [PDF]

Physical Review D, 1991
Boiling of strange-quark matter is studied assuming baryon chemical equilibrium between a quark phase described by the bag model, and a hadron phase described by Walecka's mean-field theory. Boiling of quark nuggets at high temperatures is shown to be much less efficient than previously believed. Thus quark nuggets with large baryon numbers may survive

A new window on Strange Quark Matter as the ground state of strongly interacting matter

, 2003
If strange quark matter is the true ground state of matter, it must have lower energy than nuclear matter. Simultaneously, two-flavour quark matter must have higher energy than nuclear matter, for otherwise the latter would convert to the former. We show,
