In 2018, images were released of a planet being formed around the star PDS 70, offering a
tantalizing glimpse into how planets come into being. However, many questions remain …

In this paper, we use a soft-sphere discrete element method code to simulate the
transmission and study the attenuation of a seismic wave. Then, we apply our findings to the …

We study experimentally the dynamical behavior of few large tracer particles placed in a
quasi-2D granular “gas” made of many small beads in a low-gravity environment. Multiple …

We describe an experiment container with light scattering and imaging diagnostics for
experiments on soft matter aboard the International Space Station (ISS). The suite of …

Dilute ensembles of granular matter (so-called granular gases) are nonlinear systems which
exhibit fascinating dynamical behavior far from equilibrium, including non-Gaussian …

When a container filled with granular material is subjected to sinusoidal vibration in
microgravity, dependent on the amplitude of the oscillation, the granulate may exhibit one of …

Strongly driven granular media are known to undergo a transition from a gas-like to a cluster
regime when the density of particles is increased. However, the main mechanism triggering …

Elastic properties of a granular packing show a nonlinear behavior determined by its
discrete structure and nonlinear inter-grain force laws. Acoustic waves show a transition …

Granular fluids, as defined by a collection of moving solid particles, is a paradigm of a
dissipative system out of equilibrium. Inelastic collisions between particles is the source of …

We present an experimental study of the dynamics of a set of magnets within a fluid in which
a remote torque applied by a vertical oscillating magnetic field transfers angular momentum …
