Possibility of Detecting Moons of Pulsar Planets through Time-of-Arrival Analysis

Lewis, Karen; Sackett, Penny; Mardling, Rosemary Anne


The perturbation caused by planet-moon binarity on the time-of-arrival signal of a pulsar with an orbiting planet is derived for the case in which the orbits of the moon and the planet-moon barycenter are both circular and coplanar. The signal consists of two sinusoids with frequency (2np-3nb) and (2np-nb), where np and nb are the mean motions of the planet and moon around their barycenter, and the planet-moon system around the host, respectively. The amplitude of the signal is the fraction sin...[Show more]
