Interior rotation modelling of the Cep pulsator HD 192575 including multiplet asymmetries
V. Vanlaer, D. M. Bowman, S. Burssens +4
Rotation plays an important role in stellar evolution. However, the mechanisms behind the transport of angular momentum in stars at various stages of their evolution are not well u…
The impact of radiative levitation on mode excitation of main-sequence B-type pulsators
R. Rehm, J. S. G. Mombarg, C. Aerts +3
Numerical computations of stellar oscillations for models representative of B-type stars predict fewer modes to be excited than observations reveal from modern space-based photomet…
A calibration point for stellar evolution from massive star asteroseismology
Siemen Burssens, Dominic M. Bowman, Mathias Michielsen +10
Massive stars are progenitors of supernovae, neutron stars and black holes. During the hydrogen-core burning phase their convective cores are the prime drivers of their evolution,…
The ESO UVES/FEROS Large Programs of TESS OB pulsators. I. Global stellar parameters from high-resolution spectroscopy
Nadya Serebriakova, Andrew Tkachenko, Sarah Gebruers +7
Modern stellar structure and evolution theory experiences a lack of observational calibrations for the interior physics of intermediate- and high-mass stars. This leads to discrepa…
The IACOB project VIII. Searching for empirical signatures of binarity in fast-rotating O-type stars
N. Britavskiy, S. Simón-Díaz, G. Holgado +6
The empirical distribution of projected rotational velocities (vsini) in massive O-type stars is characterized by a dominant slow velocity component and a tail of fast rotators. Bi…
Analysis of high-resolution FEROS spectroscopy for a sample of variable B-type stars assembled from TESS photometry
Sarah Gebruers, Andrew Tkachenko, Dominic M. Bowman +8
Spectroscopic data are necessary to break degeneracies in asteroseismic modelling of the interior structure in high- and intermediate-mass stars. We derive precise photospheric ste…
Polarimetric detection of nonradial oscillation modes in the beta Cephei star beta Crucis
Daniel V. Cotton, Derek L. Buzasi, Conny Aerts +11
Here we report the detection of polarization variations due to nonradial modes in the beta Cephei star beta Crucis. In so doing we confirm 40-year-old predictions of pulsation-indu…
Internal mixing of rotating stars inferred from dipole gravity modes
May G. Pedersen, Conny Aerts, Péter I. Pápics +7
During most of their life, stars fuse hydrogen into helium in their cores. The mixing of chemical elements in the radiative envelope of stars with a convective core is able to repl…
Photometric detection of internal gravity waves in upper main-sequence stars. II. Combined TESS photometry and high-resolution spectroscopy
D. M. Bowman, S. Burssens, S. Simón-Díaz +5
Context. Massive stars are predicted to excite internal gravity waves (IGWs) by turbulent core convection and from turbulent pressure fluctuations in their near-surface layers. The…
Variability of OB stars from TESS southern Sectors 1-13 and high-resolution IACOB and OWN spectroscopy
S. Burssens, S. Simón-Díaz, D. M. Bowman +6
Lack of high-precision long-term continuous photometric data for large samples of stars has prevented the large-scale exploration of pulsational variability in the OB star regime.…
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…
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…
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…
