Merging Criteria for Planetesimal Collisions

In the standard scenario of planet formation, terrestrial planets, ice giants, and cores of gas giants are formed by the accumulation of planetesimals. However, there are few N-body simulation

New HST data and modeling reveal a massive planetesimal collision around Fomalhaut

TLDR
It is found that Fomalhaut b has faded in brightness and grown in extent, with motion consistent with an escaping orbit, and suggestions that the source is a dispersing cloud of dust, produced by a massive collision between two planetesimals in an extrasolar planetary system are confirmed.

Calculation and Research of Space-Temporal Characteristics of Attack Abrases of Asteroids by Orbital Means

A development of work to combat the asteroid hazard requires construction and study of areas of outer space in which moving spacecraft-interceptors can affect asteroids. In this paper, such areas are

Systematic investigations of high‐pressure polymorphs in shocked ordinary chondrites

Shock‐induced melting textures and high‐pressure polymorphs in 178 ordinary chondrites of all chemical groups and petrologic types were investigated. The shock‐induced melting modes were classified

Active Mass Ejection for Asteroid Manipulation and Deflection

The dynamics of asteroid deflection and manipulation using mass ejection are examined. First, a linearized small angular velocity and inertia tensor deviation model for close-to-principal-axis rota...

Formation of Asteroid Families by Catastrophic Disruption: Simulations with Fragmentation and Gravitational Reaccumulation

This paper builds on preliminary work in which numerical simulations of the collisional disruption of large asteroids (represented by the Eunomia and Koronis family parent bodies) were performed and

Scale Effects in Strength-Dominated Collisions of Rocky Asteroids

Abstract The application of laboratory collision experimental results to the larger scales of asteroid impacts is complicated by the fact that the dynamic strength of rock typically decreases as the

Catastrophic Disruptions Revisited

Abstract We use a smooth particle hydrodynamics method to simulate colliding rocky and icy bodies from centimeter scale to hundreds of kilometers in diameter in an effort to define self-consistently
