Evolution of a Water-rich Atmosphere Formed by a Giant Impact on an Earth-sized Planet
The Astrophysical Journal, 2023 The atmosphere of a terrestrial planet that is replenished with secondary gases should have accumulated hydrogen-rich gas from its protoplanetary disk.

The Astronomical Journal, 2023 We present an analysis of a volume-complete sample of 363 mid-to-late M dwarfs within 15 pc of the Sun with masses between 0.1 and 0.3 M _⊙ observed by TESS within sectors 1–42. The median stellar mass of the sample is 0.17 M _⊙ .

Terrestrial planet compositions controlled by accretion disk magnetic field
Progress in Earth and Planetary Science, 2021 Terrestrial planets (Mercury, Venus, Earth, and Mars) are differentiated into three layers: a metallic core, a silicate shell (mantle and crust), and a volatile envelope of gases, ices, and, for the Earth, liquid water.

On the formation of terrestrial planets in hot-Jupiter systems [PDF]
, 2006 We present a series of calculations aimed at examining how an inner system of planetesimals/protoplanets, undergoing terrestrial planet formation, evolves under the influence of a giant planet undergoing inward type II migration through the region ...

Mars: a small terrestrial planet [PDF]
The Astronomy and Astrophysics Review, 2016 Mars is characterized by geological landforms familiar to terrestrial geologists. It has a tenuous atmosphere that evolved differently from that of Earth and Venus and a differentiated inner structure. Our knowledge of the structure and evolution of Mars has strongly improved thanks to a huge amount of data of various types (visible and infrared ...

Simulations for Terrestrial Planets Formation [PDF]
Proceedings of the International Astronomical Union, 2009 AbstractWe investigate the formation of terrestrial planets in the late stage of planetary formation using two-planet model. At that time, the protostar has formed for about 3 Myr and the gas disk has dissipated. In the model, the perturbations from Jupiter and Saturn are considered.

Numerical simulations for terrestrial planets formation
EPJ Web of Conferences, 2011 We investigate the formation of terrestrial planets in the late stage of planetary formation using two-planet model. At that time, the protostar has formed for about 3 Myr and the gas disk has dissipated.

The Survival Rate of Ejected Terrestrial Planets with Moons [PDF]
, 2007 During planet formation, a gas giant will interact with smaller protoplanets that stray within its sphere of gravitational influence. We investigate the outcome of interactions between gas giants and terrestrial-sized protoplanets with lunar-sized ...

The Astrophysical Journal, 2023 We model the early stages of planet formation in the solar system, including continual planetesimal formation, and planetesimal and pebble accretion onto planetary embryos in an evolving disk driven by a disk wind.

Stochasticity & Predictability in Terrestrial Planet Formation [PDF]
, 2016 Terrestrial planets are thought to be the result of a vast number of gravitational interactions and collisions between smaller bodies. We use numerical simulations to show that practically identical initial conditions result in a wide array of final ...
