ASTROPHYSICS: NEW ASTROPHYSICS DATA HAVE BEEN REPORTED BY D.M. SEDRAKIAN AND CO-AUTHORS
Science Letter
February 10, 2009
According to recent research from Yerevan, Armenia, "The
Ginzburg-Landau equations are derived for the magnetic and gluomagnetic
gauge fields of nonabelian semi-superfluid vortex filaments in
color superconducting cores of neutron stars containing a diquark
CFL condensate. The interaction of the diquark CFL condensate with
the magnetic and gluomagnetic gauge fields is taken into account."
"The asymptotic values of the energies of these filaments are
determined from the quantization conditions. It is shown that a
lattice of semi-superfluid vortex filaments with a minimal quantum
of circulation develops in the quark superconducting core during
rotation of the star," wrote D.M. Sedrakian and colleagues (see also
Astrophysics).
The researchers concluded: "The magnetic field in the core of this
vortex is on the order of 10(18) G. A cluster of proton vortices,
which develops in the hadron phase surrounding every superfluid neutron
vortex owing to an entrainment effect, creates new semi-superfluid
vortex filaments with a minimal quantum of circulation in the quark
superconducting core."
Sedrakian and colleagues published their study in Astrophysics
(Vortex structure of neutron stars with CFL quark cores. Astrophysics,
2008;51(4):544-558).
