Determining mass accretion and jet mass-loss rates in post-asymptotic giant branch binary systems

Dylan Bollen, Devika Kamath, Orsola De Marco +2

Aims. In this study, we determine the morphology and mass-loss rate of jets emanating from the companion in post-asymptotic giant branch (post-AGB) binary stars with a circumbinary…

Magnetically driven winds from accretion disks in post-asymptotic giant branch binaries

Olivier Verhamme, Jacques Kluska, Jonathan Ferreira +4

Context. Jets are commonly detected in post-asymptotic giant branch (post-AGB) binaries and originate from an accretion process onto the companion of the post-AGB primary. These je…

The structure of jets launched from post-AGB binary systems

Dylan Bollen, Devika Kamath, Hans Van Winckel +4

We focus on post-asymptotic giant branch (post-AGB) binaries and study the interaction between the different components of these complex systems. These components comprise the post…

The spectroscopic binaries RV Tauri and DF Cygni

Rajeev Manick, Devika Kamath, Hans Van Winckel +7

Aim: The focus of this paper is on two famous but still poorly understood RV Tauri stars: RV Tau and DF Cyg. We aim at confirming their suspected binary nature and deriving their o…

Jet parameters for a diverse sample of jet-launching post-AGB binaries

Dylan Bollen, Devika Kamath, Hans Van Winckel +2

Jets are a commonly observed phenomenon in post-asymptotic giant branch (post-AGB) binaries. Due to the orbital motion of the binary, the jet causes variable absorption in the Balm…

VLTI images of circumbinary disks around evolved stars

Jacques Kluska, Rik Claes, Akke Corporaal +13

The new generation of VLTI instruments (GRAVITY, MATISSE) aims to produce routinely interferometric images to uncover the morphological complexity of different objects at high angu…

A spatio-kinematic model for jets in post-AGB stars

Dylan Bollen, Devika Kamath, Hans Van Winckel +1

Aims. We aim to determine the geometry, density gradient, and velocity structure of jets in post-asymptotic giant branch (post-AGB) binaries. Methods. Our high cadence time series…
