Terrestrial Planet Formation in the Inclined Systems: Application to OGLE-2006-BLG-109L System

In this work, we extensively investigate the terrestrial planetary formation for the inclined planetary systems (considering the OGLE-2006-BLG-109L system as prototype) in the late stage. In the simulations, we show that the occurrence of terrestrial planets is quite common, in the final assembly stage. Moreover, we find that 40% of the runs finally occupy one planet in the habitable zone (HZ). On the other hand, the numerical results also indicate that the inner region of the planetesimal disk, ranging from $\sim 0.1$ to 0.3 AU, plays an important role in building up terrestrial planets. By examining all simulations, we note that the survivals are located either between 0.1$\sim$1.0 AU or beyond 7 AU, or at the 1:1 mean motion resonance of OGLE-2006-BLG-109Lb at $\sim$2.20 AU. The outcomes suggest that it may exist moderate possibility for the inclined systems to harbor terrestrial planets, even planets in the HZs.
