The Best Guess: Testing new and old formalisms for the common envelope against observations
Riley Thai, Amanda Karakas, Zara Osborn +4
We present a systematic test of formalisms for common envelope evolution by forward-modelling observable post-common envelope binaries. We compare predictions from the -formalis…

Using Binary Population Synthesis to Calculate the Yields of Low- and Intermediate-Mass Binary Populations at Low Metallicity
Zara Osborn, Amanda Karakas, Devika Kamath +3
Asymptotic giant branch (AGB) stars are important to chemical evolution at metallicity () as they contribute significantly to the produc…

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…
