In brief, the book offers a comprehensive investigation of asteroid impacts and shapes, making it a uniquely valuable resource.
The author parallelizes the code with high parallelization efficiency; accordingly, it can be used to conduct high-resolution simulations with the aid of supercomputers and clarify the shapes of small remnants produced through the catastrophic destruction of asteroids.This book describes numerical simulations of collisions between asteroids, based on a unique numerical code developed by the author. Development of a Numerical Simulation Method for Rocky Body Impacts and Theoretical Analysis of Aste The author also shows that asteroid collisions under certain conditions can produce the extremely elongated shape of an interstellar minor body, 1I/âOumuamua. The author demonstrates that flat asteroids can only be produced by impacts involving objects with similar mass and low velocity, which suggests that the flat asteroids in our solar system were created in the planet formation era and have kept their shapes until today.
