Description
An understanding of differentially rotating relativistic stars is key
to many areas of astrophysics, in particular to the emission of
gravitational waves. A newly born, proto-neutron star or a compact
remnant of neutron stars binary merger are expected to rotate
differentially and to be important sources of gravitational
radiation. A highly accurate, multidomain spectral code is used in
order to construct sequences of general relativistic, differentially
rotating neutron stars in axisymmetry and stationarity. The high
level of accuracy and stability of the code enable us to study stars
with maximal masses and high rotation profiles. We investigate the
solution space corresponding to broad ranges of degree of differential
rotation and stellar densities. We find various types of configurations,
which were not considered in previous work, mainly due to numerical limitations.
We study the effects of an equation of state and the degree of differential
rotation on properties of rotating neutron stars.
