GJ 357 d: Potentially Habitable World or Agent of Chaos?

The Astronomical Journal, 2023
Multiplanet systems provide important laboratories for exploring dynamical interactions within the range of known exoplanetary system architectures. One such system is GJ 357, consisting of a low-mass host star and three orbiting planets, the outermost ...

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.

Mercury’s Hidden Past: Revealing a Volatile-dominated Layer through Glacier-like Features and Chaotic Terrains

The Planetary Science Journal, 2023
The discovery of global elemental volatile compositions, sublimation hollows, and chaotic terrains has significantly reshaped our understanding of Mercury’s geology.

Implications of the TTV-detection of close-in terrestrial planets around M stars for their origin and dynamical evolution

EPJ Web of Conferences, 2011
It has been shown that an Earth-size planet or a super-Earth, in resonance with a transiting Jupiter-like body around an M star, can create detectable TTV signals (Kirste & Haghighipour, 2011).

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.

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.

Building Terrestrial Planets [PDF]

Annual Review of Earth and Planetary Sciences, 2012
This article reviews our current understanding of terrestrial planet formation. The focus is on computer simulations of the dynamical aspects of the accretion process. Throughout the review, we combine the results of these theoretical models with geochemical, cosmochemical, and chronological constraints to outline a comprehensive scenario of the early
