Terrestrial planet formation. [PDF]

open access: yesProc 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]

open access: yesScientific 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 Impact of Extended CO2 Cross Sections on Temperate Anoxic Planet Atmospheres [PDF]

open access: yesThe Astrophysical Journal
Our interpretation of terrestrial exoplanet atmospheric spectra will always be limited by the accuracy of the data we use as input in our forward and retrieval models.

The Kinetic Monte Carlo Model of the Auroral Electron Precipitation into N2-O2 Planetary Atmospheres

open access: yesUniverse, 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

open access: yesThe 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

open access: yesAtmosphere, 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.
