Hyperons in neutron-star cores and two-solar-mass pulsar
I. Bednarek, P. Haensel, J. L. Zdunik +2
Recent measurement of mass of PSR J1614-2230 rules out most of existing models of equation of state (EOS) of dense matter with high-density softening due to hyperonization or a pha…
Compression of matter in the center of accreting neutron stars
M. Bejger, J. L. Zdunik, P. Haensel +1
To estimate the feasibility of dense-matter phase transition, we studied the evolution of the central density as well as the baryon chemical potential of accreting neutron stars. W…
Implications of the measured parameters of PSR J1903+0327 for its progenitor neutron star
M. Bejger, M. Fortin, P. Haensel +1
Using the intrinsic PSR J1903+0327 parameters evaluated from radio observations (mass, rotation period and dipole magnetic field deduced from the timing properties) we calculate th…
Formation scenarios and mass-radius relation for neutron stars
J. L. Zdunik, P. Haensel
Neutron star crust, formed via accretion of matter from a companion in a low-mass X-ray binary (LMXB), has an equation of state (EOS) stiffer than that of catalyzed matter. At a gi…
