Terrestrial planet formation. [PDF]
Proc Natl Acad Sci U S A, 2011 Advances in our understanding of terrestrial planet formation have come from a multidisciplinary approach. Studies of the ages and compositions of primitive meteorites with compositions similar to the Sun have helped to constrain the nature of the building blocks of planets.

Terrestrial planet and asteroid belt formation by Jupiter–Saturn chaotic excitation [PDF]
Scientific Reports, 2023 The terrestrial planets formed by accretion of asteroid-like objects within the inner solar system’s protoplanetary disk. Previous works have found that forming a small-mass Mars requires the disk to contain little mass beyond ~ 1.5 au (i.e., the disk ...

The Kinetic Monte Carlo Model of the Auroral Electron Precipitation into N2-O2 Planetary Atmospheres
Universe, 2022 Auroral events are the prominent manifestation of solar/stellar forcing on planetary atmospheres. They are closely related to the energy deposition by and evolution of planetary atmospheres, and their observations are widely used to analyze the ...

Takeout and Delivery: Erasing the Dusty Signature of Late-stage Terrestrial Planet Formation
The Astrophysical Journal, 2023 The formation of planets like Earth is expected to conclude with a series of late-stage giant impacts that generate warm dusty debris, the most anticipated visible signpost of terrestrial planet formation in progress.

Non-Thermal Nitric Oxide Formation in the Earth’s Polar Atmosphere
Atmosphere, 2023 Auroral events are the prominent manifestation of solar/stellar forcing on planetary atmospheres because they are closely related to the stellar energy deposition by and evolution of planetary atmospheres.

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.
