Query: Dynamics and gravitational-wave emission of neutron-star merger remnants   The coalescence of a neutron-star binary is likely to result in the formation
of a neutron-star merger remnant for a large range of binary mass
configurations. The massive merger remnant shows strong oscillations, which are
excited by the merging process, and emits gravitational waves. Here we discuss
possibilities and prospects of inferring unknown stellar properties of neutron
stars by the detection of postmerger gravitational-wave emission, which thus
leads to constraints of the equation of state of high-density matter. In
particular, the dominant oscillation frequency of the postmerger remnant
provides tight limits to neutron-star radii. We mention first steps towards a
practical implementation of future gravitational-wave searches for the
postmerger emission. Moreover, we outline possibilities to estimate the unknown
maximum mass of nonrotating neutron stars from such types of measurements.
Finally, we review the origin and scientific implications of secondary peaks in
the gravitational-wave spectrum of neutron-star mergers and differences in the
dynamical behavior of the postmerger remnant depending on the binary
configuration. These considerations lead to a unified picture of the
post-merger gravitational-wave emission and the post-merger dynamics.
