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…
