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 …

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 …

Photonic lanterns (PLs) are tapered waveguides that gradually transition from a multimode
fiber geometry to a bundle of single-mode fibers (SMFs). They can efficiently couple …

We report new total-intensity visible-light high-contrast imaging of the TW Hya disk taken
with the Space Telescope Imaging Spectrograph (STIS) on the Hubble Space Telescope …

Reference star differential imaging (RDI) is a powerful strategy for high-contrast imaging.
Using example observations taken with the vortex coronagraph mode of Keck/NIRC2 in …

Context. Transition disks offer the extraordinary opportunity to look for newly born planets
and to investigate the early stages of planet formation. Aim. In this context we observed the …

Context. In recent years, our understanding of giant planet formation progressed
substantially. There have even been detections of a few young protoplanet candidates still …

Context.(Pre-) Transitional disks show gaps and cavities that can be related to ongoing
planet formation. According to theory, young embedded planets can accrete material from …

ABSTRACT The James Webb Space Telescope (JWST), currently scheduled to launch in
2021, will dramatically advance our understanding of exoplanetary systems with its ability to …

Gap-like structures in protoplanetary disks are likely related to planet formation processes. In
this paper, we present and analyze high-resolution (0.17′′× 0.11′′) 1.3 mm ALMA …
