Effect of non-spherical projectiles on the structure of porous dust aggregates formed by coagulation
Lucas Kolanz, Davide Lazzati
Cosmic dust is ubiquitous in the universe, yet the structure and geometry of individual grains remain poorly understood. The existence of non-spherical, fluffy, and even fractal gr…

Effect of temperature on the structure of porous dust aggregates formed by coagulation
Lucas Kolanz, Davide Lazzati, Job Guidos
The source of high redshift dust is currently under debate. One possibility are the ejecta of pair-instability and core collapse supernovae. However, it is uncertain how much newly…

Discrete element simulations of self-gravitating rubble pile collisions: the effects of non-uniform particle size and rotation
Job Guidos, Lucas Kolanz, Davide Lazzati
We present a novel implementation of a soft sphere, discrete elements code to simulate the dynamics of self-gravitating granular materials. The code is used to study the outcome of…
