Jupiter's Decisive Role in the Inner Solar System's Early Evolution [PDF]
, 2015 The statistics of extrasolar planetary systems indicate that the default mode of planet formation generates planets with orbital periods shorter than 100 days, and masses substantially exceeding that of the Earth.

Binary formation in planetesimal disks. II. Planetesimals with a mass spectrum [PDF]
Publications of the Astronomical Society of Japan, 2014 Abstract Many massive objects have been found in the outer region of the solar system. How they were formed and evolved has not been well understood, although there have been intensive studies of the accretion process of terrestrial planets. One of the mysteries is the existence of binary planetesimals with near-equal mass components and

From planetesimals to planets with N-body simulations in the giant-planet formation region
Astronomy & AstrophysicsThe cores of wide-orbit giant planets can form via pebble accretion if large planetesimals form in the outer regions of protoplanetary discs at sufficiently early times.

, 2011 By logging encounters between planetesimals and planets we compute the distribution of encounters in a numerically integrated two planet system that is migrating due to interactions with an exterior planetesimal belt. Capture of an irregular satellite in

The Astrophysical Journal, 2023 Recent observations suggest that the first stages of planet formation likely take place in the Class 0/I phase of young stellar object evolution, when the star and the disk are still embedded in an infalling envelope.

Can dust coagulation trigger streaming instability?
, 2014 Streaming instability can be a very efficient way of overcoming growth and drift barriers to planetesimal formation. However, it was shown that strong clumping, which leads to planetesimal formation, requires a considerable number of large grains.

Planet Formation in Circumbinary Configurations: Turbulence Inhibits Planetesimal Accretion [PDF]
, 2012 The existence of planets born in environments highly perturbed by a stellar companion represents a major challenge to the paradigm of planet formation.

Metallicity of the Massive Protoplanets Around HR 8799 If Formed by Gravitational Instability
, 2009 The final composition of giant planets formed as a result of gravitational instability in the disk gas depends on their ability to capture solid material (planetesimals) during their 'pre-collapse' stage, when they are extended and cold, and contracting ...

An unsupervised machine learning approach to iron meteorite classification
Meteoritics &Planetary Science, EarlyView.Abstract Iron meteorites are usually classified manually using bivariate elemental plots. This study extends iron meteorite classification into multi‐element space. We present a computational method for the classification of iron meteorites by applying unsupervised machine learning using density‐based cluster analysis.
