VLTI/PIONIER imaging of post-AGB binaries. An INSPIRING hunt for inner rim substructures in circumbinary discs
Toon De Prins, Akke Corporaal, Jacques Kluska +10
We image the detailed inner rim morphology for a sample of post-AGB circumbinary discs observed using NIR interferometry. At resolutions down to ~1-2 mas (corresponding to ~1-10 AU…
Bridging stellar evolution and planet formation: from birth, to survivors of the fittest, to the second generation of planets
Akke Corporaal, Toon De Prins, Léa Planquart +10
Stars and planets form, live, and evolve in unison. Throughout the life of a star, dusty circumstellar discs and stellar outflows influence the further evolution of both the star(s…
Technetium-rich M Stars: Prime diagnostics of recent third dredge-up events on the Asymptotic Giant Branch
Shreeya Shetye, Sophie Van Eck, Alain Jorissen +6
Context. Technetium (Tc)-rich M-type stars have been known for over 45 years. However, the origin of Tc in these stars, particularly its detection without the concomitant detection…
Circumbinary disc interactions and stochastic dust obscuration in the post-asymptotic-giant-branch binary HD 213985
Krystian Ilkiewicz, Lea Planquart, Tomek Kaminski +1
HD 213985 is an eccentric binary system with a post-AGB primary and a jet-launching secondary star. We confirm that the system photometric variability is likely due to obscuration…
