The Dawes review 2: nucleosynthesis and stellar yields of low-and intermediate-mass single stars

AI Karakas, JC Lattanzio - Publications of the Astronomical Society of …, 2014 - cambridge.org
The chemical evolution of the Universe is governed by the chemical yields from stars, which
in turn are determined primarily by the initial stellar mass. Even stars as low as 0.9 M⊙ can …

Learning about the intermediate neutron-capture process from lead abundances

M Hampel, AI Karakas, RJ Stancliffe… - The Astrophysical …, 2019 - iopscience.iop.org
Lead (Pb) is predominantly produced by the slow neutron-capture process (s process) in
asymptotic giant branch (AGB) stars. In contrast to significantly enhanced Pb abundances …

Optically visible post-AGB stars, post-RGB stars and young stellar objects in the Large Magellanic Cloud

D Kamath, PR Wood… - Monthly Notices of the …, 2015 - academic.oup.com
We have carried out a search for optically visible post-asymptotic giant branch (post-AGB)
stars in the Large Magellanic Cloud (LMC). First, we selected candidates with a mid-IR …

The 21 μm and 30 μm emission features in carbon-rich objects

K Volk, GC Sloan, KE Kraemer - Astrophysics and Space Science, 2020 - Springer
We review the observational properties and possible carriers of the 21 and 30 μm features
seen in the spectra of evolved carbon-rich objects. The 30 μm feature is generally taken to …

candidates in the Small Magellanic Cloud (SMC). First, we used mid-IR observations from …

Application of a theory and simulation-based convective boundary mixing model for AGB star evolution and nucleosynthesis

U Battino, M Pignatari, C Ritter, F Herwig… - The Astrophysical …, 2016 - iopscience.iop.org
The s-process nucleosynthesis in Asymptotic giant branch (AGB) stars depends on the
