Kinematic Evidence of an Embedded Protoplanet in HD 142666 Identified by Machine Learning

The Astrophysical Journal, 2023
Observations of protoplanetary disks have shown that forming exoplanets leave characteristic imprints on the gas and dust of the disk. In the gas, these forming exoplanets cause deviations from Keplerian motion, which can be detected through molecular ...

Dust Size Growth and Settling in a Protoplanetary Disk

, 2006
We have studied dust evolution in a quiescent or turbulent protoplanetary disk by numerically solving coagulation equation for settling dust particles, using the minimum mass solar nebular model.

Satellites and Small Bodies With ALMA: Insights Into Solar System Formation and Evolution

AGU Advances, Volume 6, Issue 6, December 2025.
Abstract Our understanding of the formation and evolution of planetary systems has made major advances in the past decade. This progress has been driven in large part by the Atacama Large Millimeter/submillimeter Array (ALMA), which has given us an unprecedented view of solar system bodies themselves, and of the structure and chemistry of forming ...

The Empirical and Radiative Transfer Hybrid (EaRTH) Disk Model: Merging Analyses of Protoplanetary Dust Disk Mineralogy and Structure

The Astrophysical Journal
Our understanding of how exoplanets form and evolve relies on analyses of both the mineralogy of protoplanetary disks and their detailed structures; however, these key complementary aspects of disks are usually studied separately.

Protoplanetary disk lifetimes vs stellar mass and possible implications for giant planet populations

, 2015
We study the dependence of protoplanetary disk evolution on stellar mass using a large sample of young stellar objects in nearby young star-forming regions. We update the protoplanetary disk fractions presented in our recent work (paper I of this series)

The composition of the protosolar disk and the formation conditions for comets [PDF]

, 2015
Conditions in the protosolar nebula have left their mark in the composition of cometary volatiles, thought to be some of the most pristine material in the solar system.

Parent body thermal metamorphism of enstatite chondrites: Disentangling the effects of shock melting

Meteoritics &Planetary Science, Volume 60, Issue 12, Page 2828-2863, December 2025.
Abstract Enstatite chondrites (ECs) formed on at least two parent bodies, EH and EL. After the accretion of the EC parent bodies, EC material was subjected to varying degrees of parent body thermal metamorphism (measured by petrologic types 3–6), due to heat released by radioactive isotope decay.

Shedding Light on the Origin of the Broken Misaligned Circumtriple Disk around GW Ori

The Astrophysical Journal Letters
We revisit the origin of the observed misaligned rings in the circumtriple disk around GW Ori. Previous studies appeared to disagree on whether disk breaking is caused by the differential precession driven in the disk by the triple star system.
