Stellar nucleosynthesis in the era of large surveys: S-process polluted binaries in GALAH DR4
A. Escorza, S. Vitali, D. Godoy-Rivera +11
Binary interactions during the AGB phase can lead to the formation of chemically peculiar stars with overabundances of s-process elements. Only a few hundreds of these stars have b…
JWST MIRI-MRS observations of the Red Rectangle: AIB class transformation in the outer nebula
A. Ebenbichler, P. Moraga Baez, A. Candian +8
Aims: We characterize the mid-infrared spectrum of the outer regions of the Red Rectangle nebula to probe the carbonaceous dust and molecular content beyond the circumbinary disk.…
CO observations in rotating circumbinary post-AGB disks
I. Gallardo Cava, J. Alcolea, H. Van Winckel +3
There is a group of post-AGB stars that are part of a binary system and that show a significant NIR excess. These systems are known to host disks with Keplerian or quasi-Keplerian…
Resolving the mass transfer in the symbiotic recurrent nova T Coronae Borealis
L. Planquart, A. Jorissen, H. Van Winckel
T Coronae Borealis (T CrB) is a symbiotic recurrent nova with an 80-year recurrence interval whose next eruption is imminent. We aim to resolve the accretion mechanism of the binar…
