The solid content of circumstellar disks is inherited from the interstellar medium: dust
particles of at most a micrometer in size. Protoplanetary disks are the environment where …

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 …

Context. Young circumstellar disks are the birthplaces of planets. Their study is of prime
interest to understand the physical and chemical conditions under which planet formation …

Newly forming protoplanets are expected to create cavities and substructures in young, gas-
rich protoplanetary disks,–, but they are difficult to detect as they could be confused with disk …

This review addresses the state of research that employs astronomical (remote sensing)
observations of solids (“dust”) in young circumstellar disks to learn about planet formation …

We present the first part of our Disks ARound T Tauri Stars with SPHERE (DARTTS-S)
survey: observations of eight T Tauri stars that were selected based on their strong (sub) …

Context. The observation of planets in their formation stage is a crucial but very challenging
step in understanding when, how, and where planets form. PDS 70 is a young pre-main …

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 …

It has been suggested that the gaps and cavities recently discovered in transitional disks are
opened by planets. To explore this scenario, we combine two-dimensional two fluid (gas+ …

Transitional disks are objects whose inner disk regions have undergone substantial
clearing. The Spitzer Space Telescope produced detailed spectral energy distributions …
