MATISSE unveils a dusty disc in the interior of EP Aquarii. First evidence of a misaligned hierarchical triple system with a central AGB star?
J. Alonso-Hernández, C. Paladini, C. Sánchez Contreras +26
Aims. We have mapped the dust and molecular gas emission distributions in the vicinity (a few stellar radii) of the asymptotic giant branch (AGB) star EP\,Aquarii, with a previousl…
Abundance of heavy r-process elements in CEMP-rs stars: The role of the i-process
A. M. Riyas, D. Karinkuzhi, S. Van Eck +6
Carbon-enhanced metal-poor (CEMP) stars are ancient stars enriched in carbon and heavy elements. Some of these stars exhibit enhanced s-process and/or r-process elements, hence are…
Formation of Ba stars : impact of wind Roche lobe overflow and circumbinary disk in shaping the orbital parameters
Pawel Krynski, L. Siess, A. Jorissen +1
After more than three decades of investigation, the distribution of Ba stars in the e-log P diagram still defies our understanding. Recent smooth particle hydrodynamic simulations…
A new dimension in the variability of AGB stars: convection patterns size changes with pulsation
A. Rosales-Guzmán, J. Sanchez-Bermudez, C. Paladini +16
Stellar convection plays an important role in atmospheric dynamics, wind formation and the mass-loss processes in Asymptotic Giant Branch (AGB) stars. However, a direct characteriz…
Fundamental parameters of 16 late-type stars derived from their angular diameter measured with VLTI/AMBER
P. Cruzalèbes, A. Jorissen, Y. Rabbia +7
Thanks to their large angular dimension and brightness, red giants and supergiants are privileged targets for optical long-baseline interferometers. Sixteen red giants and supergia…
Radiative hydrodynamics simulations of red supergiant stars. III. Spectro-photocentric variability, photometric variability, and consequences on Gaia measurements
A. Chiavassa, E. Pasquato, A. Jorissen +8
Context. It has been shown that convection in red supergiant stars gives rise to large granules causing surface inhomogeneities together with shock waves in the photosphere. The re…
