Tomography of cool giant and supergiant star atmospheres III. Validation of the method on VLTI/AMBER observations of the Mira star S Ori
Kateryna Kravchenko, Markus Wittkowski, Alain Jorissen +5
The knowledge of the structure and dynamics of AGB-star atmospheres is crucial to better understand the mass loss. The tomographic method, that relies on the design of spectral mas…
Tomography of cool giant and supergiant star atmospheres II. Signature of convection in the atmosphere of the red supergiant star Cep
K. Kravchenko, A. Chiavassa, S. Van Eck +4
Red supergiants are cool massive stars and are the largest and the most luminous stars in the universe. They are characterized by irregular or semi-regular photometric variations,…
Stellar Astrophysics and Exoplanet Science with the Maunakea Spectroscopic Explorer (MSE)
Maria Bergemann, Daniel Huber, Vardan Adibekyan +70
The Maunakea Spectroscopic Explorer (MSE) is a planned 11.25-m aperture facility with a 1.5 square degree field of view that will be fully dedicated to multi-object spectroscopy. A…
Spectroscopic binaries among AGB stars from HERMES/Mercator: the case of V Hya
A. Jorissen, S. Van Eck, T. Merle +1
We report on our search for spectroscopic binaries among a sample of AGB stars. Observations were carried out in the framework of the monitoring of radial velocities of (candidate)…
When binaries keep track of recent nucleosynthesis: The Zr - Nb pair in extrinsic stars as an s-process diagnostic
D. Karinkuzhi, S. Van Eck, A. Jorissen +9
Barium stars are s-process enriched giants. They owe their chemical peculiarities to a past mass transfer phase. During which they were polluted by their binary companion, which at…
