The Role of Strangeness in Astrophysics - an Odyssey through Strange Phases [PDF]

J.Phys.G28:1853-1860,2002, 2001
The equation of state for compact stars is reviewed with special emphasis on the role of strange hadrons, strange dibaryons and strange quark matter. Implications for the properties of compact stars are presented. The importance of neutron star data to constrain the properties of hypothetic particles and the possible existence of exotic phases in dense

Recent progresses in strange quark stars

Frontiers in Astronomy and Space Sciences
According to the hypothesis that strange quark matter may be the true ground state of matter at extremely high densities, strange quark stars should be stable and could exist in the Universe. It is possible that pulsars may actually be strange stars, but

Strangeness in Neutron Stars [PDF]

Nucl.Phys. A754 (2005) 335-344, 2003
We discuss the role of strangeness on the internal constitution and structural properties of neutron stars. In particular, we report on recent calculations of hyperon star properties derived from microscopic equations of state for hyperonic matter. Next, we discuss the possibility of having a strange quark matter core in a neutron star, or the possible

Superbursts from Strange Stars

, 2005
Recent models of carbon ignition on accreting neutron stars predict superburst ignition depths that are an order of magnitude larger than observed. We explore a possible solution to this problem, that the compact stars in low mass X-ray binaries that ...

Strange Exotic States and Compact Stars [PDF]

, 2006
We discuss the possible appearance of strange exotic multi-quark states in the interior of neutron stars and signals for the existence of strange quark matter in the core of compact stars.

Radial oscillations of strange quark stars admixed with condensed dark matter [PDF]

, 2017
We compute the 20 lowest frequency radial oscillation modes of strange stars admixed with condensed dark matter. We assume a self-interacting bosonic dark matter, and we model dark matter inside the star as a Bose-Einstein condensate.

Thermal Evolution and Light Curves of Young Bare Strange Stars [PDF]

, 2002
The cooling of a young bare strange star is studied numerically by solving the equations of energy conservation and heat transport for both normal and superconducting strange quark matter inside the star.

Fast spinning strange stars: Possible ways to constrain interacting quark matter parameters [PDF]

, 2016
For a set of equation of state (EoS) models involving interacting strange quark matter, characterized by an effective bag constant (B_eff) and a perturbative quantum chromodynamics corrections term (a_4), we construct fully general relativistic ...

Functional variation among LPMOs revealed by the inhibitory effects of cyanide and buffer ions

FEBS Letters, EarlyView.
This study addresses the inhibition of lytic polysaccharide monooxygenases (LPMOs) by cyanide and explains how and why the magnitude of observed inhibitory effects depends on the way LPMO reactions are setup and on the type of LPMO. Enzymes known as lytic polysaccharide monooxygenases (LPMOs) are mono‐copper polysaccharide‐degrading peroxygenases that ...

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
