We review recent works on the dynamics of circumbinary accretion, including time variability,
angular momentum transfer between the disk and the binary, and the secular evolution of …

Star and planet formation are the complex outcomes of gravitational collapse and angular
momentum transport mediated by protostellar and protoplanetary disks. In this review, we …

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 …

Protoplanetary disks are quasi-steady structures whose evolution and dispersal determine
the environment for planet formation. I review the theory of protoplanetary disk evolution and …

We use multiscale smoothed particle hydrodynamic simulations to study the inflow of gas
from galactic scales (∼ 10 kpc) down to≲ 0.1 pc, at which point the gas begins to resemble …

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

To determine the origin of the spiral structure observed in the dust continuum emission of
Elias 2–27 we analyze multiwavelength continuum ALMA data with a resolution of∼ 0 farcs …

Context. The protoplanetary disk around the F-type star HD 135344B (SAO 206462) is in a
transition stage and shows many intriguing structures both in scattered light and thermal …

We present analytic calculations of angular momentum transport and gas inflow in galaxies,
from scales of∼ kpc to deep inside the potential of a central massive black hole (BH). We …

Recent direct imaging discoveries suggest a new class of massive, distant planets around A
stars. These widely separated giants have been interpreted as signs of planet formation …
