EWOCS VII : Unveiling the faint diffuse X-ray emission in Westerlund 1
Albacete-Colombo J. F., Andersen M., De Becker M. +16
Westerlund 1 (Wd 1) is the closest supermassive star cluster to the Sun, with over 100,000 stars of all spectral types down to brown dwarfs. This population strongly heats the surr…
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…
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…
EWOCS-IV: 1Ms ACIS Chandra observation of the supergiant B[e] star Wd1-9
K. Anastasopoulou, M. G. Guarcello, J. J. Drake +21
Supergiant B[e] (sgB[e]) stars are exceptionally rare objects, with only a handful of confirmed examples in the Milky Way. The evolutionary pathways leading to the sgB[e] phase rem…
