Phase transitions and the mass-radius curves of relativistic stars

Spin - down of Relativistic Stars with Phase Transitions and PSR

Spin - down of Relativistic Stars with Phase Transitions and PSR J 0537 - 6910

An abstract should be given Using a highly accurate numerical code, we study the spin down of rotating relativistic stars, undergoing a quark decon-finement phase transition. Such phase transitions have been suggested to yield an observable signal in the braking index of spinning-down pulsars, which is based on a " backbending " behaviour of the moment of inertia. We focus on a particular equat...

Constraining the Mass & Radius of Neutron Stars in Globular Clusters

We analyze observations of eight quiescent low-mass X-ray binaries in globular clusters and combine them to determine the neutron star mass-radius curve and the equation of state of dense matter. We determine the effect that several uncertainties may have on our results, including uncertainties in the distance, the atmosphere composition, the neutron star maximum mass, the neutron star mass dis...

Phase transitions, Kauzmann curves, and inverse melting.

Walter Kauzmann's classic 1948 review of liquid supercooling and glass formation drew attention to the temperatures at which (by extrapolation) enthalpies and entropies of liquid and crystal phases would appear to become equal. In the temperature-pressure (T, p) plane, the collection of such 'Kauzmann temperatures' generate characteristic curves. The present study examines the connection of tho...

NUMERICAL SIMULATIONS OF THE PHASE TRANSITIONS IN CLUSTERS

We have studied the phase transitions in atomic clusters by molecular dynamics simulation, assuming Lennard-Jones interatomic pair potential. Calculations are performed by DAP parallel computer. The results are analyzed by simulating their orientational distribution plots (dot-plot), and neutron diffraction patterns. It is shown that all the main features of the bulk phase transitions are e...
