The Aromatic Infrared Bands around the Wolf-Rayet Binary WR140 Revealed by JWST
Kotomi Taniguchi, Ryan M. Lau, Takashi Onaka +12
We have analyzed the aromatic infrared bands (AIBs) in the 6-11.2 m range around the Wolf-Rayet binary WR140 (d=1.64 kpc) obtained with the James Webb Space Telescope (JWST) Mid…
The Serpent Eating Its Own Tail: Dust Destruction in the Apep Colliding-Wind Nebula
Ryan M. T. White, Benjamin J. S. Pope, Peter G. Tuthill +5
Much of the carbonaceous dust observed in the early universe may originate from colliding wind binaries (CWBs) hosting hot, luminous Wolf-Rayet (WR) stars. Downstream of the shock…
The formation and evolution of dust in the colliding-wind binary Apep revealed by JWST
Yinuo Han, Ryan M. T. White, Joseph R. Callingham +4
Carbon-rich Wolf-Rayet (WR) stars are significant contributors of carbonaceous dust to the galactic environment, however the mechanisms and conditions for formation and subsequent…
Carbon-rich dust injected into the interstellar medium by Galactic WC binaries survives for hundreds of years
Noel D. Richardson, Micaela Henson, Emma P. Lieb +23
Some carbon-rich Wolf-Rayet stars (WC stars) show an infrared excess from dust emission. Dust forms in the collision of the WC wind with a companion star's wind. As this dust is ca…
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…
