Multiplicity of Massive Stars at Low Metallicity: Early Results from the BLOeM Campaign

T. Shenar, J. Bodensteiner, M. Abdul-Masih, F. Backs et autres

Massive stars at low metallicity (Z) play a central role in shaping the high-redshift Universe, yet their multiplicity remains poorly constrained. The Binarity at Low Metallicity (BLOeM) campaign is a two-year survey of 929 stars in the Small Magellanic Cloud with the …

Photometric detection of internal gravity waves in upper main-sequence stars

Pieterjan Van Daele, Mathias Michielsen, T. Van Reeth

Context. Massive main-sequence stars have convective cores and radiative envelopes, but can also have sub-surface convection zones caused by partial ionisation zones. However, the convective properties of such regions strongly depend on opacity and therefore a star’s metallicity. Non-rotating 1D evolution models …

Photometric detection of internal gravity waves in upper main-sequence stars. IV. Comparable stochastic low-frequency variability in SMC, LMC, and Galactic massive stars

D. M. Bowman, Pieterjan Van Daele, Mathias Michielsen, T. Van Reeth

Massive main-sequence stars have convective cores and radiative envelopes, but also sub-surface convection zones caused by partial ionisation. However, the convective properties depend on opacity and a star's metallicity. Non-rotating 1D evolution models of main-sequence stars with the metallicity of the SMC …
