Free-floating planets (FFPs) are the lightest products of star formation and they carry
important information on the initial conditions of the environment in which they were formed …

We report the statistical properties of stars, brown dwarfs and multiple systems obtained from
the largest radiation hydrodynamical simulation of star cluster formation to date that resolves …

We report the statistical properties of stars, brown dwarfs and multiple systems obtained from
the largest hydrodynamical simulation of star cluster formation to date that resolves masses …

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 characterize the binary population in the young and nearby OB association Scorpius
OB2 (Sco OB2) using available observations of visual, spectroscopic, and astrometric …

We present the results of a survey for stellar and substellar companions to 82 young stars in
the nearby OB association Upper Scorpius. This survey used nonredundant aperture mask …

We summarize observational results on the stellar population and star formation history of
the Scorpius-Centaurus OB Association (Sco OB2), the nearest region of recent massive star …

Many, possibly most, stars form in binary and higher order multiple systems. Therefore, the
properties and frequency of binary systems provide strong clues to the star-formation …

We have carried out sensitive 1.3 mm observations of 20 young brown dwarfs in the Taurus
star-forming region, representing the largest sample of young substellar objects targeted in a …

Increasing discoveries of new planets beyond our solar system are invigorating the quest for
new knowledge and understanding of the birth of stars and planets. This new volume in the …
