Protoplanetary disks surrounding young stars are the birth place of planets. Of particular
interest are the transition disks with large inner dust cavities of tens of au, hinting at the …

High-contrast adaptive optics (AO) imaging is a powerful technique to probe the
architectures of planetary systems from the outside-in and survey the atmospheres of self …

Transition disks with large inner dust cavities are thought to host massive companions.
However, the disk structure inside the companion orbit and how material flows toward an …

Circumbinary disks are found in a variety of astrophysical scenarios, spanning binary star
formation to accreting supermassive black hole binaries. Depending on the characteristics of …

Context. Understanding the diversity of planets requires studying the morphology and
physical conditions in the protoplanetary disks in which they form. Aims. We aim to study the …

We present 3D hydrodynamical models of the HD 142527 protoplanetary disc, a bright and
well-studied disc that shows spirals and shadows in scattered light around a 100 au gas …

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 …

Protoplanetary disks with large inner dust cavities are thought to host massive planetary or
substellar companions. These disks show asymmetries and rings in the millimeter …

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 investigate whether the rings, lopsided features and horseshoes observed at millimetre
(mm) wavelengths in transitional discs can be explained by the dynamics of gas and dust at …
