Long-Lived Inverse Chirp Signals from Core-Collapse in Massive Scalar-Tensor Gravity

Abstract / Resumo 

We model stellar core collapse in massive scalar-tensor theories of gravity. The presence of a mass term for the scalar field allows for dramatic increases in the radiated gravitational wave signal and may stretch out the signal to last for years or even centuries. There are several potential smoking gun signatures of a departure from general relativity associated with this process. These signatures could show up within existing LIGO-Virgo searches.
