Are There Terrestrial Planets Lurking in the Outer Solar System? [PDF]
The Astrophysical Journal Letters, 2023 Motivated by recent measurements of the free-floating-planet mass function at terrestrial masses, we consider the possibility that the solar system may have captured a terrestrial planet early in its history.

Constructing the secular architecture of the solar system II: the terrestrial planets [PDF]
Astronomy and Astrophysics, 2009 We investigate the dynamical evolution of the terrestrial planets during the planetesimal-driven migration of the giant planets. A basic assumption of this work is that giant planet migration occurred after the completion of terrestrial planet formation, such as in the models that link the former to the origin of the Late Heavy Bombardment.

Can narrow discs in the inner Solar system explain the four terrestrial planets? [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT A successful Solar system model must reproduce the four terrestrial planets. Here, we focus on (1) the likelihood of forming Mercury and the four terrestrial planets in the same system (a 4-P system); (2) the orbital properties and masses of each terrestrial planet; and (3) the timing of Earth’s last giant impact and the mass ...

Constraining the Formation of the Four Terrestrial Planets in the Solar System [PDF]
Astrophysical Journal, 2019 Abstract To reproduce the orbits and masses of the terrestrial planets (analogs) of the solar system, most studies scrutinize simulations for success as a batch. However, there is insufficient discussion in the literature on the likelihood of forming planet analogs simultaneously in the same system (analog system). To address this issue,

A Resonant Beginning for the Solar System’s Terrestrial Planets
The Astrophysical JournalIn the past two decades, transit surveys have revealed a class of planets with thick atmospheres—sub-Neptunes—that must have completed their accretion in protoplanet disks.

Formation of the terrestrial planets in the solar system around 1 au via radial concentration of planetesimals [PDF]
Astronomy and Astrophysics, 2018 Context. No planets exist inside the orbit of Mercury and the terrestrial planets of the solar system exhibit a localized configuration. According to thermal structure calculation of protoplanetary disks, a silicate condensation line (~1300 K) is located around 0.1 au from the Sun except for the early phase of disk evolution, and planetesimals could ...

Did the terrestrial planets of the solar system form by pebble accretion?
Earth and Planetary Science LettersThe dominant accretion process leading to the formation of the terrestrial planets of the Solar System is a subject of intense scientific debate. Two radically different scenarios have been proposed. The classic scenario starts from a disk of planetesimals which, by mutual collisions, produce a set of Moon to Mars-mass planetary embryos.
