Planetesimal disk evolution driven by embryo-planetesimal gravitational scattering [PDF]
The Astronomical Journal, 2002 The process of gravitational scattering of planetesimals by a massive protoplanetary embryo is explored theoretically. We propose a method to describe the evolution of the disk surface density, eccentricity, and inclination caused by the embryo ...

High-resolution Study of Planetesimal Formation by Gravitational Collapse of Pebble Clouds [PDF]
The Astrophysical Journal, 2023 Planetary embryos are built through the collisional growth of 10–100 km-sized objects called planetesimals, a formerly large population of objects, of which asteroids, comets, and Kuiper Belt objects represent the leftovers from planet formation in our ...

Kozai effect on planetesimal accretion in highly inclined binaries [PDF]
EPJ Web of Conferences, 2011 Planet formation in highly inclined binaries is a complex issue. The Kozai mechanism plays an important role in this situation, since it will lead to high eccentricity and high relative impact velocity of planetesimals, thus hinder the planetesimal ...

The Astrophysical JournalContinuing our initiative on advancing the calculations of planetesimal accretion in the core-accretion model, we present here the results of our recent study of the contributions of planetesimals around and beyond the orbit of Saturn.

Possible Ribose Synthesis in Carbonaceous Planetesimals [PDF]
Life, 2022 The origin of life might be sparked by the polymerization of the first RNA molecules in Darwinian ponds during wet-dry cycles. The key life-building block ribose was found in carbonaceous chondrites.

Dynamics and Accretion of Planetesimals [PDF]
Progress of Theoretical and Experimental Physics, 2012 We review the basic dynamics and accretion of planetesimals by showing N-body simulations. The orbits of planetesimals evolve through two-body gravitational relaxation: viscous stirring increases the random velocity and dynamical friction realizes the ...

Low strength and a shared size distribution connect the hot and cold Kuiper belt populations [PDF]
Nature CommunicationsUnderstanding how the observed size distribution of Kuiper Belt objects emerged from the primordial planetesimal population remains a major challenge in planetary science.

Recurrent planetesimal formation in an outer part of the early solar system [PDF]
Scientific ReportsThe formation of planets in our solar system encompassed various stages of accretion of planetesimals that formed in the protoplanetary disk within the first few million years at different distances to the sun.

Small planetesimals in a massive disk formed Mars
Icarus, 2013 Mars is likely to be a planetary embryo formed through collisions with planetesimals, which can explain its small mass and rapid formation timescale obtained from 182Hf-182$W chronometry. In the classical theory of planet formation, the final embryo mass

Growth and thermal evolution of icy planetesimals
Earth, Planets and SpaceIcy planetesimals are thought to contribute to the volatile inventory of terrestrial planets and serve as building blocks of icy bodies in the outer Solar System.
