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…
Gaia-ESO Survey: massive stars in the Carina Nebula. II. The spectroscopic analysis of the O-star population
S. R. Berlanas, L. Mahy, A. Herrero +9
The new census of massive stars in the Carina nebula reveals the presence of 54 apparently single O-type stars in the Car OB1 association, an extremely active star-forming region w…
Red supergiant stars in binary systems II. Confirmation of B-type companions of red supergiants in the Small Magellanic Cloud using Hubble ultra-violet spectroscopy
L. R. Patrick, D. J. Lennon, A. Schootemeijer +5
Red supergiant stars (RSGs) represent the final evolutionary phase of the majority of massive stars and hold a unique role in testing the physics of stellar models. Eighty eight RS…
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…
EWOCS-II: X-ray properties of the Wolf-Rayet stars in the young Galactic super star cluster Westerlund 1
K. Anastasopoulou, M. G. Guarcello, E. Flaccomio +20
We present the most comprehensive and deepest X-ray study to date of the properties of the richest Wolf-Rayet (WR) population observed in a single stellar cluster, Westerlund 1 (Wd…
Barbá 2: A new supergiant-rich Galactic stellar cluster
J. Maíz Apellániz, I. Negueruela
We present a new supergiant-rich stellar cluster hidden by extinction and christen it as Barbá 2, in honor of its discoverer Rodolfo Barbá. The cluster is at a distance of $7.39^{+…
