Triple star system 'can reveal secrets of gravity'

They found a pulsar with two white dwarfs all packed in a space smaller than Earth's orbit of the Sun.
...
"The gravitational perturbations imposed on each member of this system by the others are incredibly pure and strong."

By precisely timing the arrival of the pulses, the scientists were able to calculate the geometry of the system and the masses of the stars.
...
High-precision timing of the pulsar's "lighthouse" flashes will let astronomers hunt for deviations in the equivalence principle at a sensitivity several orders of magnitude greater than ever before, said astronomer Prof Ingrid Stairs of the University of British Columbia.
