Heavy-element synthesis in AGB and post-AGB stars of low mass [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1986
Les anomalies d'abondance des elements lourds dans de nombreuses geantes rouges de faible masse montrent l'evidence qu'une forme de melange entre enveloppes et interieurs de telles etoiles est dominant a cette phase de l'evolution ...

Keplerian disks and outflows around binary post-AGB stars

open access: yes, 2022
Poster contribution for the XV SEA (2022). There is a class of binary post-AGB stars that systematically shows evidence of the presence of disks. All of them present a remarkable NIR excess and the narrow CO line profiles characteristic of rotating disks.

Binaries in AGB and post-AGB stars at high resolution

open access: yes, 2019
Binary stellar systems are very interesting cosmic laboratories, as they are related to many astrophysical phenomena, from the genesis of SNIa in post common envelope systems, to gravitational waves. They are also the most likely explanation of the formation of non-spherical axisymmetric PNe, a long standing problem in the field of late stellar ...

Circumstellar emission and absorption from post-AGB stars

open access: yes, 1998
We present the results of multi-wavelength observations, involving IUE, ground-based observations, and ISO, to study the circumstellar environment of two binary post-AGB stars, HR 4049 and HD 213985, at different orbital phases. These objects offer a unique opportunity to probe the nature of dust in absorption as well as in emission.
