PDS 70 is a unique system in which two protoplanets, PDS 70 b and c, have been
discovered within the dust-depleted cavity of their disk, at∼ 22 and 34 au, respectively, by …

We present K-band interferometric observations of the PDS 70 protoplanets along with their
host star using VLTI/GRAVITY. We obtained K-band spectra and 100 μas precision …

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 …

Context. In recent decades, direct imaging has confirmed the existence of substellar
companions (exoplanets or brown dwarfs) on wide orbits (> 10 au) around their host stars. In …

Context. Large surveys with new-generation high-contrast imaging instruments are needed
to derive the frequency and properties of exoplanet populations with separations from~ 5 to …

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 L'-band imaging of the PDS 70 planetary system with Keck/NIRC2 using the new
infrared pyramid wave front sensor. We detected both PDS 70 b and c in our images, as well …

Even though tens of directly imaged companions have been discovered in the past decades,
the number of directly confirmed multiplanet systems is still small. Dynamical analysis of …

Context. Embedded planets are potentially the cause of substructures, such as gaps and
cavities, observed in the continuum images of several protoplanetary discs. Likewise, gas …
