Fast rotation of neutron stars and equation of state of dense matter
P. Haensel, J. L. Zdunik, M. Bejger
Fast rotation of compact stars (at submillisecond period) and, in particular, their stability, are sensitive to the equation of state (EOS) of dense matter. Recent observations of…
Strong first-order phase transition in a rotating neutron star core and the associated energy release
J. L. Zdunik, M. Bejger, P. Haensel +1
We calculate the energy release associated with a strong first-order phase transition, from normal phase N to an "exotic" superdense phase S, in a rotating neutron star. Such a pha…
Two branches of neutron stars - reconciling a 2M_sun pulsar and SN1987A
P. Haensel, M. Bejger, J. L. Zdunik
The analysis of SN1987A led Brown and Bethe (1995) to conclusion, that the maximum mass of cold neutron stars is low, M_max ~ 1.5M_sun. Such a low M_max, due to a kaon condensation…
Rotation at 1122 Hz and the neutron star structure
M. Bejger, P. Haensel, J. L. Zdunik
Recent observations of XTE J1739-285 suggest that it contains a neutron star rotating at 1122 Hz. Such rotation imposes bounds on the structure of neutron star in XTE J1739-285. Th…
Phase transitions in rotating neutron stars cores: back bending, stability, corequakes and pulsar timing
J. L. Zdunik, M. Bejger, P. Haensel +1
The back-bending phenomenon for compact stars is studied by means of analytical equations of state, for both constant-pressure phase transitions and the transitions through the mix…
Spin-up of the hyperon-softened accreting neutron stars
J. L. Zdunik, P. Haensel, M. Bejger
We study the spin-up of the accreting neutron stars with a realistic hyperon-softened equation of state. Using precise 2-D calculations we study the evolutionary tracks of accretin…
