Prospects for Gravitational Wave Measurement of ZTFJ1539+5027

Understand

The short-period eclipsing binary ZTFJ1539+5027 discovered by Burdge et al.

• (2019) will be a strong gravitational-wave source for the Laser Interferometer Space Antenna (LISA).
• We study how well LISA will constrain the parameters of this system by analyzing simulated gravitational wave data, and find that LISA observations will significantly improve measurements of the distance and inclination of the source, and allow for novel constraints to be placed on the speed of gravity.
