 Abstract: Bulk viscosity in nuclear and strange quark matter arises from 
 electroweak processes as the system is driven out of chemical equilibrium.
  This dissipative mechanism plays a crucial role in two distinct astrophys
 ical regimes during the coalescence of compact star binaries. First\, duri
 ng the inspiral phase of strange quark stars\, bulk-viscous dissipation le
 ads to tidal heating\, which induces a measurable cumulative phase shift i
 n the gravitational waveform. Second\, bulk viscosity contributes to the d
 amping of strong internal baryon density oscillations in post-merger remna
 nts. This damping can significantly affect the kilohertz (kHz) gravitation
 al wave emissions\, providing a potential signature for next-generation de
 tectors. In this talk\, I discuss how bulk viscosity is generated in neutr
 on star matter and its potential impact on gravitational wave radiation fr
 om compact star mergers.    Alternative online link: https://meeting.
