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

Properties of strange-matter stars [PDF]

AIP Conference Proceedings, 1995
This paper deals with an investigation of the properties of hypothetical strange‐matter stars, which are composed of u, d, s, quark matter whose energy per baryon number lies below the one of 56Fe (Witten’s strange matter hypothesis). Observable quantities which allow to distinguish such objects from their ‘‘conventional’’ counterparts, neutron stars ...

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 ...

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:

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,

Strangelets and strange quark matter [PDF]

Nuclear Physics A, 1998
The properties of finite lumps of strange quark matter (strangelets) with emphasis on the two scenarios of producing strange matter in relativistic heavy ion collisions are summarized. As an outlook, the possibility of short-lived strange composites and charmed matter are discussed for coming heavy ion experiments.

Effects of density-dependent quark mass on phase diagram of three-flavor quark matter

, 2005
Considering the density dependence of quark mass, we investigate the phase transition between the (unpaired) strange quark matter and the color-flavor-locked matter, which are supposed to be two candidates for the ground state of strongly interacting ...
