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…
Runaway OB stars within 1 kpc of the Sun
Juan Martinez Garcia, Nicholas Wright, Alexis Quintana
Runaway stars are high-velocity stars ejected from their birth environments that can provide insights into the kinematic history of the stellar cluster they were ejected from. We d…
EWOCS-VI: Probing the hidden intermediate-mass population of Westerlund 1
C. Ordenes-Huanca, A. Bayo, M. Guarcello +11
Context: Westerlund 1 (Wd1), the most massive young star cluster in the Milky Way, is an excellent laboratory for studying star formation and early stellar evolution in a starburst…
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…
A census of OB stars within 1 kpc and the star formation and core collapse supernova rates of the Milky Way
Alexis L. Quintana, Nicholas J. Wright, Juan Martínez García
OB stars are crucial for our understanding of Galactic structure, star formation, stellar feedback and multiplicity. In this paper we have compiled a census of all OB stars within…
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…
Constraining Stellar Rotation at the Zero-Age Main Sequence with TESS
S. T. Douglas, P. A. Cargile, S. P. Matt +5
The zero-age main sequence (ZAMS) is a critical phase for stellar angular momentum evolution, as stars transition from contraction-dominated spin-up to magnetic wind-dominated spin…
