A general theory of planet formation has been a topic of intense study over many years. The
interest in such a theory emerges naturally from asking the question of where our planet …

Planets are born from the gas and dust discs surrounding young stars. Energetic radiation
from the central star can drive thermal outflows from the discs atmospheres, strongly …

Context. Most disks observed at high angular resolution show signs of substructures, such
as rings, gaps, arcs, and cavities, in both the gas and the dust. To understand the physical …

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 …

Aims. We want to find the distribution of initial conditions that best reproduces disc
observations at the population level. Methods. We first ran a parameter study using a 1D …

Context. Crystalline silicates are an important tracer of the evolution of dust, the main
building block of planet formation. In an inner protoplanetary disk, amorphous silicates are …

High-resolution spectra of typical wind diagnostics ([O i] 6300 Å and other forbidden
emission lines) can often be decomposed into multiple components: high-velocity …

ABSTRACT A necessary first step for dust removal in protoplanetary disc winds is the
delivery of dust from the disc to the wind. In the case of ionized winds, the disc and wind are …

We aim to understand the effect of stellar evolution on the evolution of protoplanetary disks.
We focus in particular on the disk evolution around intermediate-mass (IM) stars, which …

Context. Winds in protoplanetary disks play an important role in their evolution and
dispersal. However, the physical process that is actually driving the winds is still unclear (ie …
