Since Protostars and Planets VI (PPVI), our knowledge of the global properties of
protoplanetary and debris disks, as well as of young stars, has dramatically improved. At the …

Accretion through circumstellar disks plays an important role in star formation and in
establishing the properties of the regions in which planets form and migrate. The …

Context. In the last 15 years different ground-based spectroscopic surveys have been
started (and completed) with the general aim of delivering stellar parameters and elemental …

The mass accretion rate, Ṁ acc, is a key quantity for the understanding of the physical
processes governing the evolution of accretion discs around young low-mass (M⋆≲ 2.0 …

The connection between the nature of a protoplanetary disk and that of a debris disk is not
well understood. Dust evolution, planet formation, and disk dissipation likely play a role in …

Context. The diverse morphology among protoplanetary disks may result from planet-disk
interactions, suggesting the presence of planets undergoing formation. The characterization …

Ages and masses of young stars are often estimated by comparing their luminosities and
effective temperatures to pre-main-sequence stellar evolution tracks, but magnetic fields and …

Aims. In the framework of the GIARPS High-resolution Observations of T Tauri stars (GHOsT)
project, we study the accretion properties of 37 classical T Tauri stars of the Taurus-Auriga …

Determining the mechanisms that drive the evolution of protoplanetary disks is a necessary
step toward understanding how planets form. For this work, we measured the mass …

Context. Young open clusters (ages of less than 200 Myr) have been observed to exhibit
several peculiarities in their chemical compositions. These anomalies include a slightly sub …
