Long-lived inverse chirp signals from core collapse in massive scalar-tensor gravity

Understand

This letter considers 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.
• 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.
