Searching for Signatures of i-process Nucleosynthesis in Metal-Rich, Lead-rich Barium Stars
Catherine Manea, Madeleine McKenzie, Gail Zasowski +6
The intermediate neutron-capture process (-process) has been invoked to explain the peculiar compositions of carbon-enhanced metal-poor (CEMP) stars enriched in both slow- ()…
Predictions from -process AGB models of the isotopic variations of zirconium and neodymium for comparison to bulk meteorites
Maria Lugaro, Giulia C. Cinquegrana, Balázs Szányi +6
Bulk meteoritic data show isotopic variability of -neutron-capture (-process) origin in a several elements heavier than Fe. One peculiar feature is that the lighter -pr…
Probing Binary Architectures of Lithium-Rich Giants in GALAH with COSMIC and Stellar Models
Maryum Sayeed, Selina Yang, Giulia Cinquegrana +5
Surface lithium is depleted when a star goes through the first dredge-up phase, yet of red giants are found to be Li-rich. The formation mechanism for these remains uncertain…
Testing stellar yield prescriptions in OMEGA+: Implications for rising sodium abundances in young thick disc stars
Evans K. Owusu, Ashley J. Ruiter, Alex J. Kemp +8
We recently identified an upturn in [Na/Fe] for the population of Solar-type stars in the Galactic young thick disc () at super-Solar metallicity in…
Stellar Evolution in Real Time II: R Hydrae and an Open-Source Grid of >3000 Seismic TP-AGB Models Computed with MESA
Meridith Joyce, László Molnár, Giulia Cinquegrana +3
We present a comprehensive characterization of the evolved thermally pulsing asymptotic giant branch (TP-AGB) star R Hydrae, building on the techniques applied in Stellar Evolution…
Bridging the Gap between Intermediate and Massive Stars II: for the most metal-rich stars and implications for Fe CCSNe rates
Giulia C. Cinquegrana, Meridith Joyce, Amanda I. Karakas
The minimum initial mass required for a star to explode as an Fe core collapse supernova, typically denoted , is an important quantity in stellar evolution because it…
Bridging the Gap between Intermediate and Massive Stars I: Validation of MESA against the State-of-the-Art Monash Stellar Evolution Program for a 2 AGB Star
Giulia C. Cinquegrana, Meridith Joyce, Amanda I. Karakas
One--dimensional stellar structure and evolution programs are built using different physical prescriptions and algorithms, which means there can be variations between models' predi…
Modules for Experiments in Stellar Astrophysics (MESA): Time-Dependent Convection, Energy Conservation, Automatic Differentiation, and Infrastructure
Adam S. Jermyn, Evan B. Bauer, Josiah Schwab +19
We update the capabilities of the open-knowledge software instrument Modules for Experiments in Stellar Astrophysics (MESA). The new auto_diff module implements automatic different…
Solar calibration of using ÆSOPUS opacities in MESA
Giulia C Cinquegrana, Meridith Joyce
The simplistic but ubiquitous Mixing Length Theory (MLT) formalism is used to model convective energy transport within 1D stellar evolution calculations. The formalism relies on th…
The most metal-rich stars in the universe: chemical contributions of low and intermediate mass asymptotic giant branch stars with metallicities between
Giulia C. Cinquegrana, Amanda I. Karakas
Low and intermediate mass stars with super solar metallicities comprise a known portion of the universe. Yet yields for asymptotic giant branch (AGB) stars with metallicities great…
The most metal-rich asymptotic giant branch stars
Amanda Karakas, Giulia Cinquegrana, Meridith Joyce
We present new stellar evolutionary sequences of very metal-rich stars evolved with the Monash Stellar Structure code and with MESA. The Monash models include masses of $1-8M_{\odo…
