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�…

Our understanding of planet formation has been rapidly evolving in recent years. The
classical planet formation theory, developed when the only known planetary system was our�…

Context. Transition disks are protoplanetary disks with dust-depleted cavities, possibly
indicating substantial clearing of their dust content by a massive companion. For several�…

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�…

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�…

Recent spatially-resolved observations of protoplanetary disks revealed a plethora of
substructures, including concentric rings and gaps, inner cavities, misalignments, spiral�…

The detection of a wide range of substructures such as rings, cavities, and spirals has
become a common outcome of high spatial resolution imaging of protoplanetary disks, both�…

We present an overview and first results from a M-band spectroscopic survey of planet-
forming disks performed with iSHELL on the Infrared Telescope Facility, using two slits that�…

Aims. In the framework of the GIARPS High-resolution Observations of T Tauri stars (GHOsT)
project, we study the accretion properties of 37 classical T Tauri stars of the Taurus-Auriga�…

This work presents ground-based spectrally resolved water emission at R= 30,000–100,000
over infrared wavelengths covered by the JWST (2.9–12.8 μm). Two new surveys with�…
