KOI-3158: The oldest known system of terrestrial-size planets [PDF]
EPJ Web of Conferences, 2015 The first discoveries of exoplanets around Sun-like stars have fueled efforts to find ever smaller worlds evocative of Earth and other terrestrial planets in the Solar System. While gas-giant planets appear to form preferentially around metal-rich stars,

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.

Terrestrial Planet Formation: The Solar System and Other Systems [PDF]
Symposium - International Astronomical Union, 2004 Accretion of terrestrial planets and solid cores of jovian planets is discussed, based on the results of our N-body simulations. Protoplanets accrete from planetesimals through runaway and oligarchic growth until they become isolated. The isolation mass of protoplanets in terrestrial planet region is about 0.2 Earth mass, which suggests that in the ...

Constraining the Formation of the Four Terrestrial Planets in the Solar System [PDF]
The 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,

Origin of life-forming volatile elements in the inner Solar System [PDF]
, 2022 International audienceVolatile elements such as hydrogen, carbon, nitrogen and oxygen are essential ingredients to build habitable worlds like Earth, but their origin and evolution on terrestrial planets remain highly debated.

Microlensing search for extra solar planets [PDF]
, 2015 Gravitational microlensing may be used to probe distant stars for planetary companions. The presence of a planet in the vicinity of a star acting as the lens may cause a short lived anomaly in the observed lightcurve of the lensing event.

Terrestrial planet formation in extra-solar planetary systems [PDF]
Proceedings of the International Astronomical Union, 2007 AbstractTerrestrial planets form in a series of dynamical steps from the solid component of circumstellar disks. First, km-sized planetesimals form likely via a combination of sticky collisions, turbulent concentration of solids, and gravitational collapse from micron-sized dust grains in the thin disk midplane.

Modelling Atmospheric Erosion for Terrestrial Planets in the Solar System
, 2023 Since the Great Oxidation Event, the oxygen escape rate on Earth has changed over time mainly due to solar evolution. Two solar agents drive the Earth’s atmospheric erosion rate: the solar wind and the EUV radiation. The first one affects the non-thermal processes by changing the plasma conditions, and the second one affects both types of processes: by
