EWOCS-IX: JWST/NIRCam observations of Westerlund 2 - Identification of candidate substellar members

V. Almendros-Abad, M. G. Guarcello, K. Muzic +26

[Abridged] Investigating substellar populations in young massive clusters offers crucial insights into the formation of brown dwarfs (BDs) and the role of environmental conditions…

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-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…

EWOCS-III: JWST observations of the supermassive star cluster Westerlund 1

M. G. Guarcello, V. Almendros-Abad, J. B. Lovell +29

The typically large distances, extinction, and crowding of Galactic supermassive star clusters have so far hampered the identification of their very low mass members, required to e…
