Isochrone-cloud fitting of the extended Main-Sequence Turn-Off of young clusters
C. Johnston, C. Aerts, M. G. Pedersen +1
Extended main-sequence turn-offs (eMSTO) are a commonly observed property of young clusters. A global theoretical interpretation for the eMSTOs is still lacking, but stellar rotati…
New Cep pulsators discovered with K2 space photometry
S. Burssens, D. M. Bowman, C. Aerts +3
We present the discovery of three new Cep pulsators, three new pulsators with frequency groupings, and frequency patterns in a B3Ib star, all of which show pulsations with freq…
Probing the shape of the mixing profile and of the thermal structure at the convective core boundary through asteroseismology
Mathias Michielsen, May G. Pedersen, Kyle C. Augustson +2
Aims: We investigate from a theoretical perspective if space asteroseismology can be used to distinguish between different thermal structures and shapes of the near-core mixing pro…
Low-frequency gravity waves in blue supergiants revealed by high-precision space photometry
Dominic M. Bowman, Siemen Burssens, May G. Pedersen +14
Almost all massive stars explode as supernovae and form a black hole or neutron star. The remnant mass and the impact of the chemical yield on subsequent star formation and galacti…
Three-Dimensional Simulations of Massive Stars: I. Wave Generation and Propagation
P. V. F. Edelmann, R. P. Ratnasingam, M. G. Pedersen +3
We present the first three-dimensional (3D), hydrodynamic simulations of the core convection zone (CZ) and extended radiative zone spanning from 1% to 90% of the stellar radius of…
Astro2020 Science White Paper: gravity-wave asteroseismology of intermediate- and high-mass stars
Andrew Tkachenko, Conny Aerts, Dominic M. Bowman +17
The evolution of a star is driven by the physical processes in its interior making the theory of stellar structure and evolution the most crucial ingredient for not only stellar ev…
