The Antares emission nebula and mass loss of α Scorpii A

  title={The Antares emission nebula and mass loss of $\alpha$ Scorpii A},
  author={D. Reimers and H. Hagen and R. Baade and K. Braun},
  journal={Astronomy and Astrophysics},
Aims. The Antares nebula is a peculiar emission nebula seen in numerous [Fe ii] lines and in radio free-free emission, probably associated with the H ii region caused by α Sco B in the wind of α Sco A. High-resolution spectra with spatial resolution were used to study the emission line spectrum, the physical nature of the nebula and to determine the mass-loss rate of the M supergiant α Sco A. Methods. The Antares nebula was mapped with long-slit (10 �� ) and high-resolution (R = 80 000) spectra… Expand

IRC 10414: a bow-shock-producing red supergiant star ⋆
Most runaway OB stars, like the majority of massive stars residing in their parent clusters, go through the red supergiant (RSG) phase during their lifetimes. Nonetheless, although many dozens ofExpand
The inner circumstellar dust of the red supergiant Antares as seen with VLT/SPHERE/ZIMPOL
The processes by which red supergiants lose mass are not fully understood thus-far and their mass-loss rates lack theoretical constraints. The ambient surroundings of the nearby M0.5 Iab star AntaresExpand
