Scientific paper

The extrasolar system OGLE-2006-BLG-109L is the first multiple-planet system to be discovered by gravitational microlensing (Gaudi et al., 2008). This system has been described as an analog for our own solar system because the two large planets that have been detected have mass ratios, semimajor axis ratios, and equilibrium temperatures that are similar to those of Jupiter and Saturn, but the system is more compact than our own because the mass of the star is only 0.5 M⊙. We consider the orbital dynamics and calculate possible architectures that could support a habitable planet in the OGLE-2006-BLG-109L system.
