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-V: Is Wd1-72 a recent post-interaction WR+O binary?

C. J. K. Larkin, J. Mackey, H. Jin +14

The evolutionary origin of Wolf-Rayet (WR) stars at Solar metallicity is unclear. Single-star evolution from massive O stars, possibly via a Luminous Blue Variable phase, is challe…

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…

Predicting the X-ray signatures of the imminent T Coronae Borealis outburst through 3D hydrodynamic modeling

S. Orlando, L. Chomiuk, J. Drake +3

T Coronae Borealis (T CrB) is a symbiotic recurrent nova with eruptions in 1866 and 1946. Mounting evidence suggests an imminent outburst, offering a rare opportunity to observe a…

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…
