As planets form and grow within gaseous protoplanetary disks, the mutual gravitational
interaction between the disk and planet leads to the exchange of angular momentum and …

We present two new Lagrangian methods for hydrodynamics, in a systematic comparison
with moving-mesh, smoothed particle hydrodynamics (SPH), and stationary (non-moving) …

We carry out 2D viscous hydrodynamical simulations of circumbinary accretion using the
moving-mesh code AREPO. We self-consistently compute the accretion flow over a wide …

We present 1.3 mm continuum ALMA long-baseline observations at 3–5 au resolution of 10
of the brightest discs from the Ophiuchus DIsc Survey Employing ALMA (ODISEA) project …

A large planet orbiting a star in a protoplanetary disk opens a density gap along its orbit due
to the strong disk–planet interaction and migrates with the gap in the disk. It is expected that …

We study the implementation of mechanical feedback from supernovae (SNe) and stellar
mass loss in galaxy simulations, within the Feedback In Realistic Environments (FIRE) …

We explain the axisymmetric gaps seen in recent long-baseline observations of the HL Tau
protoplanetary disc with the Atacama Large Millimetre/Submillimetre Array (ALMA) as being …

We present Phantom, a fast, parallel, modular, and low-memory smoothed particle
hydrodynamics and magnetohydrodynamics code developed over the last decade for …

The filamentary nature of accretion streams found around embedded sources suggests that
protostellar disks experience heterogenous infall from the star-forming environment …

We study the torque on low-mass planets embedded in protoplanetary discs in the two-
dimensional approximation, incorporating non-isothermal effects. We couple linear …
