Grids of stellar models with rotation VIII: Models from 1.7 to 500 at metallicity
Yves Sibony, Kendall G. Shepherd, Norhasliza Yusof +12
Grids of stellar evolution models with rotation using the Geneva stellar evolution code (Genec) have been published for a wide range of metallicities. We introduce the last remaini…
Very massive star winds as sources of the short-lived radioactive isotope Al
S. Martinet, G. Meynet, D. Nandal +7
The Al short-lived radioactive nuclide is the source of the observed galactic diffuse -ray emission at 1.8 MeV. While different sources of Al have been explored, s…
Grids of stellar models with rotation VII: Models from 0.8 to 300 M at super-solar metallicity (Z = 0.020)
Norhasliza Yusof, Raphael Hirschi, Patrick Eggenberger +11
We present a grid of stellar models at super-solar metallicity (Z = 0.020) extending the previous grids of Geneva models at solar and sub-solar metallicities. A metallicity of Z =…
Convective core entrainment in 1D main sequence stellar models
L. J. A. Scott, R. Hirschi, C. Georgy +5
3D hydrodynamics models of deep stellar convection exhibit turbulent entrainment at the convective-radiative boundary which follows the entrainment law, varying with boundary penet…
Pair-Instability Supernova Simulations: Progenitor Evolution, Explosion, and Light Curves
Matthew S. Gilmer, Alexandra Kozyreva, Raphael Hirschi +2
In recent years, the viability of the pair-instability supernova (PISN) scenario for explaining superluminous supernovae has all but disappeared except for a few slowly-evolving ex…
Grids of stellar models with rotation - III. Models from 0.8 to 120 Msun at a metallicity Z = 0.002
Cyril Georgy, Sylvia Ekström, Patrick Eggenberger +11
(shortened) We provide a grid of single star models covering a mass range from 0.8 to 120 Msun with an initial metallicity Z = 0.002 with and without rotation. We discuss the impac…
