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…
Evidence for the Keplerian orbit of a close companion around a giant star
Mats Esseldeurs, Leen Decin, Joris De Ridder +31
Close companions influence stellar evolution through tidal interactions, mass transfer, and mass loss effects. While such companions are detected around young stellar objects, main…
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…
Using Binary Population Synthesis to Examine the Impact of Binary Evolution on the C, N, O, and -Process Yields of Solar-Metallicity Low- and Intermediate-Mass Stars
Zara Osborn, Amanda I. Karakas, Alex J. Kemp +3
Asymptotic giant branch (AGB) stars play a significant role in our understanding of the origin of the elements. They contribute to the abundances of C, N, and approximately …
