Binary white dwarfs and decihertz gravitational wave observations: From the Hubble constant to supernova astrophysics

Understand

Coalescences of binary white dwarfs represent a copious source of information for gravitational wave interferometers operating in the decihertz band.

• Moreover, according to the double degenerate scenario, they have been suggested to be possible progenitors of supernovae (SNe) Type Ia events.
• In this paper we discuss the detectability of gravitational waves emitted by the inspiral of double white dwarfs.
• We focus on the constraints that can be derived on the source's luminosity distance, and on other binary's parameters, such as the angular momentum orientation.
