The Best Guess: Testing new and old formalisms for the common envelope against observations
Riley Thai, Amanda Karakas, Amanda I. Karakas +8
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 …
Nova contributions to the chemical evolution of the Milky Way
Alex J. Kemp, Amanda I. Karakas, Andrew R. Casey +3
Context. The explosive burning that drives nova eruptions results in unique nucleosynthesis that heavily over-produces certain isotopes relative to the solar abundance. However, no…
Aluminium-26 production in low- and intermediate-mass binary systems
Zara Osborn, Amanda I. Karakas, Alex J. Kemp +1
Aluminium-26 is a radioactive isotope which can be synthesized within asymptotic giant branch (AGB) stars, primarily through hot bottom burning. Studies exploring Al product…
A deep dive into the Type II Globular Cluster NGC 1851
E. Dondoglio, A. P. Milone, A. F. Marino +13
About one-fifth of the Galactic globular clusters (GCs), dubbed Type II GCs, host distinct stellar populations with different heavy elements abundances. NGC 1851 is one of the most…
The messy death of a multiple star system and the resulting planetary nebula as observed by JWST
Orsola De Marco, Muhammad Akashi, Stavros Akras +66
Planetary nebulae (PNe), the ejected envelopes of red giant stars, provide us with a history of the last, mass-losing phases of 90 percent of stars initially more massive than the…
Viability of novae as sources of Galactic lithium
Alex J. Kemp, Amanda I. Karakas, Andrew R. Casey +3
Of all the light elements, the evolution of lithium (Li) in the Milky Way is perhaps the most difficult to explain. Li is difficult to synthesize and is easily destroyed, making mo…
