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

open access: yesEPJ 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).

Evolution of a Water-rich Atmosphere Formed by a Giant Impact on an Earth-sized Planet

open access: yesThe 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.

Numerical simulations for terrestrial planets formation

open access: yesEPJ 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.

Building Terrestrial Planets [PDF]

open access: yesAnnual 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

The Occurrence Rate of Terrestrial Planets Orbiting Nearby Mid-to-late M Dwarfs from TESS Sectors 1–42

open access: yesThe 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

open access: yesProgress 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.

Mars: a small terrestrial planet [PDF]

open access: yesThe 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 ...

Making the Solar System

open access: yesThe 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.
