Context. Star formation takes place in giant molecular clouds, resulting in mass-segregated
young stellar clusters composed of Sun-like stars, brown dwarfs, and massive O-type (50 …

We examine the clustering and kinematics of young stellar objects (YSOs) in the North
America/Pelican Nebulae, as revealed by Gaia astrometry, in relation to the structure and …

Context. Reconstructing the structure and history of young clusters is pivotal to
understanding the mechanisms and timescales of early stellar evolution and planet …

Context. In clustered environments, stellar encounters can liberate planets from their host
stars via close encounters. Although the detection probability of planets suggests that the …

Context. On the one hand, the second data release of the Gaia mission (Gaia DR2) has
opened a trove of astrometric and photometric data for Galactic clusters within a few …

Context. The young massive cluster Westerlund 1 offers the promise of a grand laboratory
for the study of high-mass star evolution, but its basic parameters are still poorly known …

The dominant formation mechanism of brown dwarfs and planetary-mass objects (PMOs) in
star-forming regions is presently uncertain. Do they form like stars, via the collapse and …

Context. There are a number of methods that identify stellar sub-structure in star forming
regions, but these do not quantify the degree of association of individual stars–something …

Context. Better understanding of star formation in clusters with high-mass stars requires
rigorous dynamical and spatial analyses of star-forming regions. Aims. We seek to …

The multidimensional phase space density (both position and velocity) of star-forming
regions may encode information on the initial conditions of star and planet formation …
