Accumulation of dust and ice particles into planetesimals is an important step in the planet
formation process. Planetesimals are the seeds of both terrestrial planets and the solid cores …

The formation of planets with gaseous envelopes takes place in protoplanetary accretion
discs on time scales of several million years. Small dust particles stick to each other to form …

Extreme mass ratio inspirals (EMRIs) are important sources for space-borne gravitational
wave detectors, such as the laser interferometer space antenna and TianQin. Previous EMRI …

Accretion disks around supermassive black holes (SMBHs) in active galactic nuclei (AGNs)
contain stars, stellar mass black holes, and other stellar remnants, which perturb the disk …

By performing global hydrodynamical simulations of accretion discs with driven turbulence
models, we demonstrate that elevated levels of turbulence induce highly stochastic …

The streaming instability is a promising mechanism to drive the formation of planetesimals in
protoplanetary disks. To trigger this process, it has been argued that sedimentation of solids …

The streaming instability for solid particles in protoplanetary disks is reexamined assuming
the familiar alpha (α) model for isotropic turbulence. Turbulence always reduces the growth …

We analyse the effect of stochastic torque fluctuations on the orbital evolution and the
gravitational wave (GW) emission of gas-embedded sources with intermediate and extreme …

The streaming instability is a fundamental process that can drive dust–gas dynamics and
ultimately planetesimal formation in protoplanetary discs. As a linear instability, it has been …

The streaming instability is a leading candidate mechanism to explain the formation of
planetesimals. However, the role of this instability in the driving of turbulence in …
