Core-Collapse Supernova Gravitational Wave Signature Catalog

As a service to the community and in an effort to further and nurture collaboration between supernova theorists and the gravitational wave data analysis community we provide gravitational waveform data as extracted from the various core-collapse supernova calculations performed by our group.

Here we provide gravitational wave signature data for

• Gravitational Waves from Nonrotating and Slowly Rotating Axisymmetric Core-Collapse Supernovae:
  Gravitational wave emission owing to convective overturn, anisotropic neutrino emission, and protoneutron star g-mode pulsations. The gravitational wave data are based on our Newtonian 2D (axisymmetric) neutrino-radiation hydrodynamics supernova calculations presented in Burrows et al. 2007, "Features of the Acoustic Mechanism of Core-Collapse Supernova Explosions," ApJ 665, 416, Burrows et al. 2006, "A New Mechanism for Core-Collapse Supernova Explosions," ApJ 640, 878, and Ott et al. 2006, "A New Mechanism for Gravitational Wave Emission in Core-Collapse Supernovae," PRL 96, 201102.
• Gravitational Waves from Axisymmetric Rotating Accretion-Induced Collapse and the Subsequent Supernova Evolution.
  Gravitational wave emission owing to fast rotating collapse and anisotropic neutrino emission. The gravitational wave data are based on our 2D neutrino-radiation hydrodynamic simulations of the accretion-induced collapse of oxygen-neon-magnesium white dwarfs presented in Dessart et al. 2006, "Multidimensional Simulations of the Accretion-induced Collapse of White Dwarfs to Neutron Stars," ApJ 645, 534.
• Gravitational Waves from Axisymmetric Fast Rotating Adiabatic Iron Core Collapse and Core Bounce.
  The data are based on our Newtonian 2D purely hydrodynamic simulations of the collapse of rotating presupernova iron cores presented in Ott et al. 2004, "Gravitational Waves from Axisymmetric, Rotational Stellar Core Collapse," ApJ 600, 834.
