Understanding post-red giant branch binaries through stable mass transfer
C. A. S. Moltzer, O. R. Pols, H. Van Winckel +2
Post-RGB and post-AGB binaries consist of a primary star that has recently evolved off either the RGB or AGB after losing most of its envelope, and a main-sequence companion. They…

Abundance Analysis of Chemically Depleted Post-AGB/Post-RGB Binaries with Faint Discs
Maksym Mohorian, Devika Kamath, Meghna Menon +4
Post-AGB and post-RGB binaries with stable circumbinary discs provide key insights into late stellar and disc evolution, revealing how binary interactions shape disc structure and…

s-process Enriched Post-AGB Star J003643.94-723722.1 in the SMC with an Extreme C/O Ratio and the First Precise Detection of Lead
Meghna Menon, Devika Kamath, Maksym Mohorian +6
Post-asymptotic giant branch (post-AGB) stars are exquisite tracers of s-process nucleosynthesis via their surface abundances. We present a comprehensive analysis of J003643.947…
