Low-frequency gravity waves in blue supergiants revealed by high-precision space photometry
Dominic M. Bowman,Siemen Burssens,M. G. Pedersen,Cole Johnston,Conny Aerts,Conny Aerts,B. Buysschaert,B. Buysschaert,Mathias Michielsen,Andrew Tkachenko,Tamara M. Rogers,Tamara M. Rogers,P. V. F. Edelmann,R. P. Ratnasingam,Sergio Simón-Díaz,Norberto Castro,Ehsan Moravveji,Benjamin J. S. Pope,Timothy R. White,Peter De Cat +19 more
TL;DR: In this paper, the authors report the detection of diverse variability in blue supergiants using the K2 and TESS space missions, which allow us to map the evolution of hot massive stars towards the end of their lives.
Internal mixing of rotating stars inferred from dipole gravity modes
M. G. Pedersen,M. G. Pedersen,Conny Aerts,Conny Aerts,Conny Aerts,Péter Pápics,Mathias Michielsen,Sarah Gebruers,Sarah Gebruers,Tamara M. Rogers,Tamara M. Rogers,Geert Molenberghs,Geert Molenberghs,Siemen Burssens,Stefano Garcia,Dominic M. Bowman +15 more
TL;DR: In this paper, core-to-surface mixing profiles inferred from observed dipole gravity modes in 26 rotating stars with masses between 3 and 10 solar masses are provided. But the results provide observational guidance for three-dimensional hydrodynamical simulations of transport processes in the deep interiors of stars.

Conny Aerts,Conny Aerts,Conny Aerts,Geert Molenberghs,Geert Molenberghs,Geert Molenberghs,Mathias Michielsen,M. G. Pedersen,R. Björklund,Cole Johnston,Joey S. G. Mombarg,Dominic M. Bowman,B. Buysschaert,B. Buysschaert,Péter Pápics,S. Sekaran,J. O. Sundqvist,Andrew Tkachenko,Kevin Truyaert,T. Van Reeth,E. Vermeyen +20 more
TL;DR: In this paper, the authors express their sincere appreciation to the developer teams of the MESA and GYRE codes, for making their software available to the astronomical community, and thank Aaron Dotter for his advice on how to include atomic diffusion in MESA in an optimal way for the mass range considered here.
Variability of OB stars from TESS southern Sectors 1-13 and high-resolution IACOB and OWN spectroscopy
S. Burssens,Sergio Simón-Díaz,Sergio Simón-Díaz,Dominic M. Bowman,G. Holgado,G. Holgado,Mathias Michielsen,A. de Burgos,A. de Burgos,Norberto Castro,Rodolfo H. Barbá,Conny Aerts,Conny Aerts,Conny Aerts +13 more
TL;DR: In this paper, the authors combine TESS data in the southern sky with ground-based spectroscopy to study the variability in two dimensions, mass and evolution of the stars.

The mass discrepancy in intermediate- and high-mass eclipsing binaries: The need for higher convective core masses
Andrew Tkachenko,K. Pavlovski,Cole Johnston,M. G. Pedersen,Mathias Michielsen,Dominic M. Bowman,John Southworth,V. Tsymbal,Conny Aerts +8 more
TL;DR: In this paper, the mass discrepancy in binary stars is investigated and the effect of near-core mixing on the mass of the convective core of the stars and interpret the results in the context of mass discrepancy.
