The mean temperature of the emission is 85 K, corresponding to an orbital separation from the host star of 50 AU.
A substellar object with minimum mass of 1.6 Jupiter masses and orbital separation of roughly 6.5 AU could explain the observed trend.
The primary and secondary components have nearly identical radii of about 300 m, and their orbital separation is only 1200 m.
The orbital separation varies from 2 astronomical units at periastron to 17.5 astronomical units at apastron.
This orbital separation is consistent with the in situ formation of the planet via a core accretion mechanism.
A substellar object with minimum mass of 4 Jupiter masses and orbital separation of roughly 8 AUs could explain the observed trend.
Liu et al. (2007) have proposed an alternative model, showing a very low-mass planetary object at unclear orbital separation from the neutron star.
Furthest orbital separation at apastron last occurred in May 1995 and the next will be in 2075.
They infer a mass of 20 times that of Jupiter for the perturbing object and an orbital separation of 0.08 Astronomical Units.
Its average orbital separation is at 1.33 Astronomical Units away from its star with a year of 501.75 days.
