Analytic CCSN Waveforms: 2. Accretion Disk Instabilities

Document #:

LIGO-T1100093-v2

Document type:

T - Technical notes

Abstract:

We derive the gravitational wave emission from accretion disk instabilities in long gamma-ray bursts or black-hole forming core-collapse supernovae based on simple analytic models of van Putten and Piro & Pfahl.

Notes and Changes:

Update with the following improvements:
- more detailed derivations
- change of the Piro fragmentation-type instability waveforms; the orbital angular velocity for these waveforms is now based on the sum of BH mass and fragment mass.
