The Gaia mission has opened a new window into the internal kinematics of young star clusters at the sub-km/s level, with implications for our understanding of how star clusters form and evolve. We use a sample of 28 clusters and associations with ages from 1-5 Myr, where lists of members are available from previous X-ray, optical, and infrared studies. Proper motions from Gaia DR2 reveals that at least 75% of these systems are expanding; however, rotation is only detected in one system. Typical… Expand
Gaia stellar kinematics in the head of the Orion A cloud: runaway stellar groups and gravitational infall
This work extends previous kinematic studies of young stars in the head of the Orion A cloud (OMC-1/2/3/4/5). It is based on large samples of infrared, optical, and X-ray selected pre-main-sequenceExpand
Not all stars form in clusters – Gaia-DR2 uncovers the origin of OB associations
Historically, it has often been asserted that most stars form in compact clusters. In this scenario, present-day gravitationally-unbound OB associations are the result of the expansion of initiallyExpand
A relation between the radial velocity dispersion of young clusters and their age
The majority of massive stars (> 8 M ) in OB associations are found in close binary systems. Nonetheless, the formation mechanism of these close massive binaries is not understood yet. UsingExpand

The Dynamical State of a Young Stellar Cluster
The dynamical state of the young star-forming cluster Rho Ophiuchi is considered, with emphasis on the L1688 cloud. Radial velocities are derived for 32 YSOs, with some being multi-epoch, usingExpand
The dynamics of the γ Vel cluster and nearby Vela OB2 association
The kinematics of low-mass stars in nearby OB associations can provide clues about their origins and evolution. Combining the precise positions, proper motions and parallaxes given in the second GaiaExpand
OB Associations and their origins
OB associations are unbound groups of young stars made prominent by their bright OB members, and have long been thought to be the expanded remnants of dense star clusters. They have been important inExpand
Expanding associations in the Vela-Puppis region
Context. The Vela-Puppis region is known to host the Vela OB2 association as well as several young clusters featuring OB and pre-main-sequence stars. Several spatial and kinematic subgroups have beenExpand
