TL;DR: In this article, the authors derived analytical expressions of the critical semimajor axis beyond which the satellites would not remain stable, as a function of the eccentricities of the planet, ep, and of the satellite, e sat.

TL;DR: In this article, a series of simulations of terrestrial planet formation and asteroid belt evolution starting from discs of planetesimals and planetary embryos with various radial density gradients and including Jupiter and Saturn on nearly circular and coplanar orbits were performed.

TL;DR: In this paper, the authors examined an alternative scenario for the formation of Mars in which a local depletion in the density of the protosolar nebula results in a non-uniform formation of planetary embryos and ultimately the creation of Mars-sized planets around 1.5 AU.

TL;DR: In this paper, a compound model incorporating both the principal endogenous and exogenous theories, and investigating their implications for terrestrial planet formation and water delivery was developed, and the results showed that the compound model plays an important role by showing greater advantage in the amount and time of water delivery in Earth-like planets.

TL;DR: In this paper, the authors show that the orbits of the asteroids may have been excited to their current state if Jupiter and Saturn's early orbits were chaotic, and that small perturbations could have driven them into a chaotic but stable state.
