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 …

Observational advances over the last decade have enabled high-resolution, interferometric
studies of forming multiple systems, statistical surveys of multiplicity in star-forming regions …

We review the role of stellar flybys and encounters in shaping planet-forming discs around
young stars, based on the published literature on this topic in the last 30 years. Since most …

We characterize protostellar multiplicity in the Orion molecular clouds using Atacama Large
Millimeter/submillimeter Array 0.87 mm and Very Large Array 9 mm continuum surveys …

Aims. We present high-sensitivity and high spectral-resolution NOEMA observations of the
Class 0/I binary system SVS13A, composed of the low-mass protostars VLA4A and VLA4B …

Characterizing the physical conditions at disk scales in class 0 sources is crucial for
constraining the protostellar accretion process and the initial conditions for planet formation …

Context. Gas accretion flows transport material from the cloud core onto the protostar. In
multiple protostellar systems, it is not clear if the delivery mechanism is preferential or more …

We report the analysis of circumbinary (CB) discs formed in a radiation hydrodynamical
simulation of star cluster formation. We consider both pure binary stars and pairs within triple …

Abstract We present Very Large Array (VLA) and Atacama Large Millimeter/submillimeter
Array (ALMA) observations of the close (0 farcs 3= 90 au separation) protobinary system …

We have observed the very low-mass Class 0 protostar IRAS 15398− 3359 at scales
ranging from 50 to 1800 au, as part of the Atacama Large Millimeter/Submillimeter Array …
