Long-term gravitational wave asteroseismology of supernova: from core collapse to 20 seconds postbounce

Masamitsu Mori, Yudai Suwa, Tomoya Takiwaki

We use an asteroseismology method to calculate the frequencies of gravitational waves in a long-term core-collapse supernova simulation, with a mass of 9.6 $M_{\odot }$. The simulatio…
