CERN’s HiRadMat facility restarts this week with a new experiment nicknamed “Fireball”, which will give new insights into extreme astrophysical phenomena such as gamma-ray bursts.
Low-speed impact simulations into regolith in support of asteroid sampling mechanism design I:Comparison with 1-g experiments
Asteroids Surfaces Collisional physics Granular material Sampling mechanism Geological processes Regoliths
2015/12/25
This study is carried out in the framework of sample-return missions to asteroids that use a low-speed projectile as the primary component of its sampling mechanism (e.g., JAXA’s Hayabusa and Hayabusa...
Numerical experiments with rubble piles:equilibrium shapes and spins
Asteroids Planetesimals Rotational dynamics Solid body tides Satellites of Jupiter
2015/12/25
We present numerical experiments investigating the shape and spin limits of self-gravitating “perfect” rubble piles that consist of identical, smooth, rigid, spherical particles with configurable norm...
Glycine oligomerization up to triglycine by shock experiments simulating comet impacts
comet impacts amino acids peptides shock experiments origins of life
2017/4/10
We conducted shock experiments simulating comet impacts to assess the feasibility of peptide synthesis by such a
process. We used frozen mixture of the amino acid glycine, water ice, and silicate (fo...
