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 …

Planet-forming disc evolution is not independent of the star formation and feedback process
in giant molecular clouds. In particular, OB stars emit UV radiation that heats and disperses …

Context. Previous theoretical works on planet formation around low-mass stars have often
been limited to large planets and individual systems. As current surveys routinely detect …

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

Estimates of the mass and age of young stars from their location in the HR diagram are
limited by not only the typical observational uncertainties that apply to field stars, but also by …

We present VLT/X-shooter observations of a sample of 36 accreting low-mass stellar and
substellar objects (YSOs) in the Lupus star-forming region, spanning a range in mass from …

Context. Planet formation is sensitive to the conditions in protoplanetary disks, for which
scaling laws as a function of stellar mass are known. Aims. We aim to test whether the …

The strong X-ray irradiation from young solar-type stars may play a crucial role in the
thermodynamics and chemistry of circumstellar discs, driving their evolution in the last …

We analyze the accretion properties of 21 low-mass T Tauri stars using a data set of
contemporaneous near-UV (NUV) through optical observations obtained with the Hubble …

The dependence of the mass accretion rate on the stellar properties is a key constraint for
star formation and disk evolution studies. Here we present a study of a sample of stars in the …
