-mode Oscillations for Hyperons and H-dibaryons in Neutron Stars
Rajesh Maiti, Jesper Leong, Debarati Chatterjee +1
The fundamental (-mode) oscillations of neutron stars are studied within the quark meson coupling model, a relativistic Hartree-Fock theory of dense nuclear matter, which takes…
Predictions in the superheavy region from the quark-meson coupling model QMC-III
Kay Marie M. Paglinawan, Anthony W. Thomas, Pierre A. M. Guichon +1
The Quark-Meson Coupling (QMC) model establishes a self-consistent relationship between the quark structure dynamics of a nucleon and the relativistic mean fields that arise within…
Are Neutron Stars Rich in H-dibaryons?
Jesper Leong, Anthony W. Thomas, Pierre A. M. Guichon
The possible existence of an H-dibaryon near the threshold has still not been decided experimentally. This raises the question of the potential effects on neutron stars if it…
Heavy Neutron Star Phenomenology with an H-dibaryon
Jesper Leong, Anthony W. Thomas, Pierre A. M. Guichon
The equation of state for dense nuclear matter in -equilibrium is explored including the possibility of a doubly-strange H-particle. Consistent with experimental constraints, th…
Hartree-Fock Formulation of the QMC Model at Finite Temperature
P A M Guichon, J R Stone, A W Thomas
We present, for the first time, a detailed theory of high density matter including the entire baryon octet at finite temperature, based on a fully relativistic mean field model wit…
On the Speed of Sound in Hyperonic Stars
T. F. Motta, P. A. M. Guichon, A. W. Thomas
We build upon the remarkable, model independent constraints on the equation of state of dense baryonic matter established recently by Annala et al. [1]. Using the quark-meson coupl…
On introducing Charge-Symmetry-Breaking terms to nuclear Energy Density Functionals
P. Bączyk, M. Konieczka, K. M. L. Martinez +5
The Charge-Symmetry-Breaking (CSB) character of the nucleon-nucleon interaction is well established. This work presents two different ways of introducing such effects into a nuclea…
Equation of State of Hot Dense Hyperonic Matter in the Quark-Meson-Coupling (QMC-A) model
J. R. Stone, V. Dexheimer, P. A. M. Guichon +2
We report a new equation of state (EoS) of cold and hot hyperonic matter constructed in the framework of the quark-meson-coupling (QMC-A) model. The QMC-A EoS yields results compat…
Neutron to Dark Matter Decay in Neutron Stars
T. F. Motta, P. A. M. Guichon, A. W. Thomas
Recent proposals have suggested that a previously unknown decay mode of the neutron into a dark matter particle could solve the long lasting measurement problem of the neutron deca…
Role of Hyperons in Neutron Stars
J. R. Stone, P. A. M. Guichon, A. W. Thomas
The latest observation of a Shapiro delay of the binary millisecond pulsar J1614-2230 by Demorest et al. Nature 467 1081 (2010) yielded the pulsar gravitational mass to be 1.97 +/-…
Physical Origin of Density Dependent Force of the Skyrme Type within the Quark Meson Coupling Model
P. A. M. Guichon, H. H. Matevosyan, N. Sandulescu +1
A density dependent, effective nucleon-nucleon force of the Skyrme type is derived from the quark-meson coupling model -- a self-consistent, relativistic quark level description of…
