Abstract EN
The perturbation caused by planet-moon binarity on the time-of-arrival (TOA) signal of a pulsar with an orbiting planet is derived for the case of the orbit of the planet-moon system inclined of an angle α with respect to the plane of the orbit of the planet-moon barycenter around the pulsar.
We also consider both the orbits of the moon and the planet-moon barycenter as circular.
The signal consists of three sinusoids with frequency, respectively, of (2np−3nb), (2np−nb), and (2np−3nb), where np and nb are, respectively, 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 equal to the fraction sinI[9(Mp/Mm)/16(Mp+Mm)2][r/R]5(5 sin2α/3−2sinα/3−2 cos2α/9) of the system crossing time R/c, where Mp and Mm are, respectively, the mass of the planet and the mass of the moon, r is their orbital separation, R is the distance between the host pulsar and planet-moon barycenter, I is the inclination of the orbital plane of the planet, and c is the speed of light.
