Gravitational Wave Signatures of Magnetohydrodynamically Driven Core-Collapse Supernova Explosions

Core-collapse supernovae are now expected to be opening a new branch of astronomy, gravitationalwave (GW) astronomy. Currently, long baseline laser interferometers LIGO, VIRGO, GEO600, TAMA300, AIGO and KAGRA with their international networks of observatories are beginning to take data at sensitivities where astrophysical events are predicted. For these detectors, corecollapse supernovae have been proposed as one of the most plausible sources of gravitational waves. Although the explosion mechanism of core-collapse supernovae has not been completely clarified yet, magnetohydrodynamic (MHD) explosion mechanism gathers great attention for special explosions associated with birth of magnetars instead of ordinary pulsars. By performing a series of two-dimensional, special
