Abstract:
The very first direct detection of gravitational waves from a black hole
merger opened up a new field of observation to astrophysics. In this context, previous
studies also examined upcoming core-collapse supernovae in the Local Group
of the Milky Way. Strong hints lead to the assumption that they are potential
sources of gravitational waves which we could measure with present gravitational
wave detectors on earth.
In this work, we review the current knowledge of the theory of core-collapse supernovae.
Furthermore, we deliver a summary of the physical description of gravitational
waves. Finally, we develop a simple model of a collapsing stellar core which is deformed
by rotation into an oblate spheroid. At a distance of r = 10 kpc, we could
measure linear polarized gravitation waves in order of magnitude hx ~ 1-3 x 10-21
on the equatorial plane. We show that the results are in agreement with typical
gravitational wave signals from previous core-collapse simulations.
