The Equation of State for Dense QCD and Quark Stars [PDF]
, 2002 We calculate the equation of state for degenerate quark matter to leading order in hard-dense-loop (HDL) perturbation theory. We solve the Tolman-Oppenheimer-Volkov equations to obtain the mass-radius relation for dense quark stars. Both the perturbative

Quark stars: features and findings [PDF]
The European Physical Journal C, 2006 Under extreme conditions of temperature and/or density, quarks and gluons are expected to undergo a deconfinement phase transition. While this is an ephemeral phenomenon at the ultra-relativistic heavy-ion collider (BNL-RHIC), quark matter may exist naturally in the dense interior of neutron stars.

Nonradial oscillations of quark stars [PDF]
Physical Review D, 2003 Recently, it has been reported that a candidate for a quark star may have been observed. In this article, we pay attention to quark stars with radiation radii in the reported range. We calculate nonradial oscillations of $f$-, $w$- and $w_{\rm II}$-modes.

The Chandrasekhar limit for quark stars [PDF]
Journal of Physics G: Nuclear and Particle Physics, 1999 The Chandrasekhar limit for quark stars is evaluated from simple energy balance relations, as proposed by Landau for white dwarfs or neutron stars. It has been found that the limit for quark stars depends on, in addition to the fundamental constants, the Bag constant.

Holomorphic field theories and higher algebra
Bulletin of the London Mathematical Society, EarlyView.Abstract Aimed at complex geometers and representation theorists, this survey explores higher dimensional analogs of the rich interplay between Riemann surfaces, Virasoro and Kac‐Moody Lie algebras, and conformal blocks. We introduce a panoply of examples from physics — field theories that are holomorphic in nature, such as holomorphic Chern‐Simons ...

The mixed phase quark core in massive hybrid stars
European Physical Journal C: Particles and FieldsWe investigate the properties of hybrid star and the mixed phase core to explore the radius ratio of the mixed phase in hybrid star. In the context of observed massive neutron stars (NSs), we examine the internal structure, phase transitions, and the ...

Quark-Nova Explosion inside a Collapsar: Application to Gamma Ray Bursts
Advances in Astronomy, 2009 If a quark-nova occurs inside a collapsar, the interaction between the quark-nova ejecta (relativistic iron-rich chunks) and the collapsar envelope leads to features indicative of those observed in Gamma Ray Bursts.

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 ...

Quark formation and phenomenology in binary neutron-star mergers using V-QCD
SciPost Physics, 2022 Using full 3+1 dimensional general-relativistic hydrodynamic simulations of equal- and unequal-mass neutron-star binaries with properties that are consistent with those inferred from the inspiral of GW170817, we perform a detailed study of the quark ...
