EWOCS-VIII: Internal kinematics and expansion of Westerlund 1 from VVVX proper motions
C. Ordenes-Huanca, A. Bayo, M. Guarcello +12
Westerlund 1 (Wd1) is the most massive young star cluster known in the Milky Way and a key laboratory for studying the early dynamical evolution of massive clusters. Owing to its h…
3D Rotation of the Open Cluster NGC 2516
Nicholas J. Wright, R. D. Jeffries, M. A. Whalley
We have combined Gaia astrometry with Gaia-ESO Survey radial velocities to measure the 3D rotation of the open cluster NGC 2516. We compiled a sample of 376 members with astrometry…
Uniformly-calibrated VPHAS+ photometry in the third quadrant of the Galactic plane
J. E. Drew, R. Greimel, J. Eislöffel +2
The southern Galactic plane has been mapped at optical wavelengths and at under one-arcsecond angular resolution by the VST Photometric Ha Survey of the Galactic plane and bulge (V…
Kinematic substructure in star clusters constrains star cluster formation
Becky Arnold, Nicholas J. Wright
The spatial-kinematic structure of 48 young star clusters and associations is investigated. Moran's statistic is used to quantify the degree of kinematic substructure in each r…
