The Initial Magnetic Field Distribution in AB Stars
Eoin Farrell, Adam S. Jermyn, Matteo Cantiello +1
Stars are born with magnetic fields, but the distribution of their initial field strengths remains uncertain. We combine observations with theoretical models of magnetic field evol…
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 =…
Ionizing photon production of Population III stars: effects of rotation, convection, and initial mass function
Laura J. Murphy, Jose H. Groh, Eoin Farrell +5
The first stars are thought to be one of the dominant sources of hydrogen reionization in the early Universe, with their high luminosities and surface temperatures expected to driv…
Convective core sizes in rotating massive stars: I. Constraints from solar metallicity OB field stars
S. Martinet, G. Meynet, S. Ekström +11
Spectroscopic studies of Galactic O and B stars show that many stars with masses above 8 M are observed in the HR diagram just beyond the Main-Sequence (MS) band predicte…
Grids of stellar models with rotation: V. Models from 1.7 to 120 Msun at zero metallicity
Laura J. Murphy, Jose H. Groh, Sylvia Ekstrom +10
Understanding the nature of the first stars is key to understanding the early universe. With new facilities such as JWST we may soon have the first observations of the earliest ste…
Is GW190521 the merger of black holes from the first stellar generations?
Eoin J. Farrell, Jose H. Groh, Raphael Hirschi +5
GW190521 challenges our understanding of the late-stage evolution of massive stars and the effects of the pair-instability in particular. We discuss the possibility that stars at l…
