Jet formation in post-AGB binaries: Confronting cold magnetohydrodynamic disc wind wind models with observations
Toon De Prins, Hans Van Winckel, Jonathan Ferreira +4
Aims: We consider cold self-similar magnetohydrodynamic (MHD) disc wind solutions to describe jets that are launched from the circumcompanion accretion discs in post-AGB binaries.…
Teaching the apparent motion of Sun and stars across four European countries
Hans Bekaert, Wim Van Dooren, Hans Van Winckel +7
In the context of the European Erasmus+ project Teaching ASTronomy at the Educational level (TASTE), we investigated the extent to which a learning module at school and a set of ac…
A dynamic view of V Hydrae. Monitoring of a spectroscopic-binary AGB star with an alkaline jet
L. Planquart, A. Jorissen, A. Escorza +2
The well studied carbon star V Hydrae is known to exhibit a complex asymmetric environment made of a dense equatorial wind and high-velocity outflows, hinting at its transition fro…
VELOcities of CEpheids (VELOCE) I. High-precision radial velocities of Cepheids
Richard I. Anderson, Giordano Viviani, Shreeya S. Shetye +27
This first VELOCE data release comprises 18,225 high-precision RV measurements of 258 bona fide classical Cepheids on both hemispheres collected mainly between 2010 and 2022, along…
s-process Enriched Evolved Binaries in the Galaxy and the Magellanic Clouds
Meghna Menon, Devika Kamath, Maksym Mohorian +2
Post-asymptotic giant branch stars (post-AGB) in binary systems, with typical orbital periods between ~100 to ~1000 days, result from a poorly understood interaction that terminate…
The first measurements of carbon isotopic ratios in post-RGB stars: SZ Mon and DF Cyg. E-iSpec: A spectral analysis tool to derive elemental abundances and isotopic ratios for evolved stars
Maksym Mohorian, Devika Kamath, Meghna Menon +4
Dusty post-red giant branch (post-RGB) stars are low- and intermediate-mass stars where the RGB evolution was prematurely terminated by a poorly understood binary interaction. Thes…
