After decades of fast-paced technical advances, optical/infrared (O/IR) interferometry has
seen a revolution in recent years:▪ The GRAVITY instrument at the Very Large Telescope …

Abstract Herbig Ae/Be stars are young contracting stars on the radiative track in the HR
diagram on their way to the main sequence. These stars provide a valuable link between …

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

Context. Herbig Ae/Be stars (HAeBes) have so far been studied based on relatively small
samples that are scattered throughout the sky. Their fundamental stellar and circumstellar …

To date, nearly two hundred planet-forming disks have been imaged at high resolution. Our
propensity to study bright and extended objects does, however, bias our view of the disk …

Photonic technologies offer numerous functionalities that can be used to realize
astrophotonic instruments. The most spectacular example to date is the ESO Gravity …

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 …

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 …

Context. Observations of young stars hosting transition disks show that several of them have
high accretion rates, despite their disks presenting extended cavities in their dust …

Context. The innermost astronomical unit (au) in protoplanetary disks is a key region for
stellar and planet formation, as exoplanet searches have shown a large occurrence of close …
