On the stability of bow shocks generated by red supergiants: the case of IRC-10414
D. M. -A. Meyer, V. V Gvaramadze, N. Langer +3
In this Letter, we explore the hypothesis that the smooth appearance of bow shocks around some red supergiants (RSGs) might be caused by the ionization of their winds by external s…
SALT reveals the barium central star of the planetary nebula Hen 2-39
B. Miszalski, H. M. J Boffin, D. Jones +6
Classical barium stars are binary systems which consist of a late-type giant enriched in carbon and slow neutron capture (s-process) elements and an evolved white dwarf (WD) that i…
ALMA observations of the variable 12CO/13CO ratio around the asymptotic giant branch star R Sculptoris
W. H. T. Vlemmings, M. Maercker, M. Lindqvist +7
[abridged] The 12CO/13CO ratio is often used as a measure of the 12C/13C ratio in the circumstellar environment, carrying important information about the stellar nucleosynthesis. E…
The elusive origin of Carbon-Enhanced Metal-Poor stars
C. Abate, O. R. Pols, R. G. Izzard +2
Carbon-enhanced metal-poor (CEMP) stars count for 9-25% of all the very metal-poor stars of the halo. In at least some CEMP stars the chemical enrichment is believed to be due to w…
3D Smoothed Particle Hydrodynamics Models of Betelgeuse's Bow Shock
Shazrene Mohamed, Jonathan Mackey, Norbert Langer
Betelgeuse, the bright red supergiant (RSG) in Orion, is a runaway star. Its supersonic motion through the interstellar medium has resulted in the formation of a bow shock, a comet…
Numerical models for the circumstellar medium around Betelgeuse
Jonathan Mackey, Shazrene Mohamed, Hilding R. Neilson +2
The nearby red supergiant (RSG) Betelgeuse has a complex circumstellar medium out to at least 0.5 parsecs from its surface, shaped by its mass-loss history within the past 0.1 Myr,…
