Massive Protostellar Disks as a Hot Laboratory of Silicate Grain Evolution
The Astrophysical Journal, 2023 Typical accretion disks around massive protostars are hot enough for water ice to sublimate. We here propose to utilize the massive protostellar disks for investigating the collisional evolution of silicate grains with no ice mantle, which is an ...

Journal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.Abstract CM (Mighei‐type) carbonaceous chondrites host abundant OH/H2O‐bearing phyllosilicates formed from water‐rock reactions in primitive planetesimals. Their infrared (IR) spectral features resemble those of C‐type asteroids, making laboratory analyses of CMs essential for interpreting asteroid observations.

The Astrophysical Journal, 2023 Using self-consistent models of turbulent particle growth in an evolving protoplanetary nebula of solar composition, we find that recently proposed local metallicity and Stokes number criteria necessary for the streaming instability to generate ...

Evolution of Terrestrial Planetary Bodies and Implications for Habitability
Reviews of Geophysics, Volume 63, Issue 4, December 2025.Abstract The terrestrial planetary bodies of our solar system—Mercury, Venus, Earth, and Mars—share a common origin through nebular accretion and early magma ocean differentiation, yet they diverged significantly in geological evolution, tectonic regimes, and habitability.

PLANETARY MIGRATION IN EVOLVING PLANETESIMAL DISKS [PDF]
International Journal of Modern Physics D, 2003 In the current paper, we further improved the model for the migration of planets introduced and extended to time-dependent planetesimal accretion disks by Del Popolo. In the current study, the assumption of Del Popolo, that the surface density in planetesimals is proportional to that of gas, is relaxed. In order to obtain the evolution of planetesimal

Terrestrial Planet Formation from Two Source Reservoirs
The Astronomical JournalThis work describes new dynamical simulations of terrestrial planet formation. The simulations started at the protoplanetary disk stage, when planetesimals formed and accreted into protoplanets, and continued past the late stage of giant impacts.
