Discovery of a new transitional type of evolved massive stars with hard ionizing flux
Andreas A. C. Sander, Roel R. Lefever, Joris Josiek +12
Wolf-Rayet (WR) stars are the evolved descendants of the most massive stars and show emission-line dominated spectra formed in their powerful stellar winds. Marking the final evolu…
Metal-poor single Wolf-Rayet stars: The interplay of optically thick winds and rotation
Lumen Boco, Michela Mapelli, Andreas A. C. Sander +7
The Small Magellanic Cloud (SMC) hosts 12 known Wolf-Rayet (WR) stars, seven of which are apparently single. Their formation is a challenge for current stellar evolution models bec…
Low-metallicity massive single stars with rotation. III. Source of ionization and C-IV emission in I Zw 18
Dorottya Szécsi, Frank Tramper, Brankica Kubátová +5
Chemically homogeneously evolving stars have been proposed to account for several exotic phenomena, including gravitational-wave emissions and gamma-ray bursts. Here we study wheth…
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…
