All four circumbinary (CB) protoplanetary disks orbiting short-period (P< 20 days) double-
lined spectroscopic binaries (SB2s)—a group that includes UZ Tau E, for which we present …

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 …

Context. A large portion of stars is found to be part of binary or higher-order multiple
systems. The ubiquity of planets found around single stars raises the question of whether …

We report the ALMA Cycle 2 observations of the Class I binary protostellar system L1551 NE
in the 0.9 mm continuum, C 18 O (3–2), 13 CO (3–2), SO (7 8–6 7), and CS (7–6) emission …

How does the cavity size in circumbinary discs depend on disc and binary properties? We
investigate by simulating disc cavities carved by binary companions using smoothed particle …

Context. Studying molecular species in protoplanetary disks is very useful to characterize
the properties of these objects, which are the site of planet formation. Aims. We attempt to …

The binary system GG Tau A is observed to have a circumbinary disc with a dust ring located
further out than expected, assuming a co-planar disc and a corresponding semimajor axis of …

Context. GG Tauri A is the prototype of a young triple T Tauri star that is surrounded by a
massive and extended Keplerian outer disk. The central cavity is not devoid of gas and dust …

Context. ALMA high angular resolution observations of the dust and CO emission have
already revealed signatures of protoplanets embedded in protoplanetary disks. These …

Context. Protoplanetary disks in dense, massive star-forming regions are strongly affected
by their environment. How this environmental impact changes over time is an important …
