Query: Terrestrial Planets Formation under Migration: the Systems near 4:2:1
  Mean Motion Resonance   In this work, we extensively investigate the formation of near 4:2:1 mean
motion resonances (MMRs) configuration by performing two sets of N-body
simulations. We model the eccentricity damping, gas drag, type I and type II
planetary migration of planetesimals, planetary embryos and giant planets in
the first sets. For the simulations of giant planets with type II migration,
the massive terrestrial planets, with a mass up to several Earth masses, are
likely produced in the systems. We further show that by shepherding and/or
scattering mechanisms through Jovian planet's type II migration, the
terrestrial planets and giant planets in the systems can be evolved into a near
4:2:1 MMRs. Moreover, the models are applicable to the formation of Kepler-238
and 302 systems. In the second set, we study the 4:2:1 MMRs formation in the
terrestrial planetary systems, where the planets undergo type I migration and
eccentricity damping. By considering type I migration, $\sim$ 17.1\% of the
simulations indicate that terrestrial planets are evolved into 4:2:1 MMRs.
However, this probability should depend on the initial conditions of planets.
Hence, we conclude that both type I and type II migration can play a crucial
role in close-in terrestrial planet formation.
