“The most common source for LISA is expected to be double white dwarf systems, which are binaries composed of white dwarfs in tight orbits,” said Casey McGrath, a postdoctoral researcher at the University of Maryland, Baltimore County and NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “If an exoplanet also orbits within one of these systems, its presence becomes imprinted on the gravitational wave signal in a way we’ll be able to uncover.”
