An Investigation of Non-Canonical Mixing in Red Giant Stars Using APOGEE 12C/13C Ratios Observed in Open Cluster Stars

Caroline McCormick, Steven R. Majewski, Verne V. Smith +9

Standard stellar evolution theory poorly predicts the surface abundances of chemical species in low-mass, red giant branch (RGB) stars. Observations show an enhancement of p-p chai…

Parameterisations of thermal bomb explosions for core-collapse supernovae and 56Ni production

Liliya Imasheva, H. -Thomas Janka, Achim Weiss

Thermal bombs are a widely used method to artificially trigger explosions of core-collapse supernovae (CCSNe) to determine their nucleosynthesis or ejecta and remnant properties. R…

Stellar evolution models with overshooting based on 3-equation non-local theories, II. Main-sequence models of A- and B-type stars

Felix Ahlborn, Friedrich Kupka, Achim Weiss +1

Convective overshoot mixing is a critical ingredient of stellar structure models, but is treated in most cases by ad hoc extensions of the mixing-length theory for convection. Adva…

The BAyesian STellar Algorithm (BASTA): a fitting tool for stellar studies, asteroseismology, exoplanets, and Galactic archaeology

V. Aguirre Børsen-Koch, J. L. Rørsted, A. B. Justesen +16

We introduce the public version of the BAyesian STellar Algorithm (BASTA), an open-source code written in {\tt Python} to determine stellar properties based on a set of astrophysic…

Lithium in NGC 2243 and NGC 104

Misa Aoki, Francesca Primas, Luca Pasquini +3

Our aim was to determine the initial Li content of two clusters of similar metallicity but very different ages, the old open cluster NGC 2243 and the metal-rich globular cluster NG…

Modified Gravity and the Flux-weighted Gravity-Luminosity Relationship of Blue Supergiant Stars

Eva Sextl, Rolf-Peter Kudritzki, Jochen Weller +2

We calculate models of stellar evolution for very massive stars and include the effects of modified gravity to investigate the influence on the physical properties of blue supergia…
