Barium & related stars and their white-dwarf companions I. Giant stars
A. Jorissen, H. M. J. Boffin, D. Karinkuzhi +4
This paper provides long-period and revised orbits for barium and S stars adding to previously published ones. The sample of barium stars with strong anomalies comprise all such st…
NOEMA maps the CO environment of the red supergiant Cep
M. Montargès, W. Homan, D. Keller +8
Red supergiant stars are surrounded by a gaseous and dusty circumstellar environment created by their mass loss which spreads heavy elements into the interstellar medium. The struc…
Barium & related stars and their white-dwarf companions II. Main-sequence and subgiant stars
A. Escorza, D. Karinkuzhi, A. Jorissen +12
Barium (Ba) dwarfs and CH subgiants are the less-evolved analogues of Ba and CH giants. They are F- to G-type main-sequence stars polluted with heavy elements by a binary companion…
Observational evidence of third dredge-up occurrence in S-type stars with initial masses around 1 Msun
Shreeya Shetye, Stephane Goriely, Lionel Siess +3
Context- S stars are late-type giants with spectra showing characteristic molecular bands of ZrO in addition to the TiO bands typical of M stars. Their overabundance pattern shows…
