Angular momenta of collided rarefied preplanetesimals
Sergei I. Ipatov
TL;DR
This paper investigates how collisions of rarefied preplanetesimals can generate angular momentum, shedding light on the formation of small-body binaries and trans-Neptunian objects.
Contribution
It provides a method to estimate angular momenta from preplanetesimal collisions, linking collision dynamics to binary formation in the outer solar system.
Findings
Angular momentum can be derived from collision parameters.
Collisions can produce sufficient angular momentum for binary formation.
Supports the hypothesis that trans-Neptunian binaries originate from contracting preplanetesimals.
Abstract
The angular momenta of rarefied preplanetesimals needed for formation of small-body binaries can be obtained at collisions of preplanetesimals. Trans-Neptunian objects, including trans-Neptunian binaries, could be formed from contracting rarefied preplanetesimals.
