The IACOB project: XVI. Surface helium abundances in Galactic O-type stars: indications for identifying binary interaction products
S. Simón-DÃaz, G. Holgado, C. MartÃnez-Sebastián +13
The presence of massive O-type stars with surfaces enriched by CNO-cycle products has been known since the early 1980s. For many years, internal rotational mixing was assumed to be…
Binarity at LOw Metallicity (BLOeM): a spectroscopic VLT monitoring survey of massive stars in the SMC
T. Shenar, J. Bodensteiner, H. Sana +74
Surveys in the Milky Way and Large Magellanic Cloud revealed that the majority of massive stars will interact with companions during their lives. However, knowledge of the binary p…
Evolutionary models for the Very Massive Stars in the R136 cluster of 30 Doradus in the Large Magellanic Cloud
Z. Keszthelyi, S. A. Brands, A. de Koter +2
The cluster R136 in the LMC contains a population of stars in excess of 100 M, including R136a1, the most massive star known. Very Massive Stars (VMSs) play an influential…
Binarity at LOw Metallicity (BLOeM): Multiplicity of early B-type supergiants in the Small Magellanic Cloud
N. Britavskiy, L. Mahy, D. J. Lennon +32
The blue supergiant (BSG) domain contains a large variety of stars whose past and future evolutionary paths are still highly uncertain. Since binary interaction plays a crucial rol…
RAMBO I: Project introduction and first results with uGMRT
Z. Keszthelyi, K. Kurahara, Y. Iwata +4
Magnetic hot stars can emit both coherent and incoherent non-thermal radio emission. Understanding the nature of these emissions and their connection to stellar rotation and magnet…
Binarity at LOw Metallicity (BLOeM): The multiplicity properties and evolution of BAF-type supergiants
L. R. Patrick, D. J. Lennon, F. Najarro +36
Given the uncertain evolutionary status of blue supergiant stars, their multiplicity properties hold vital clues to better understand their origin and evolution. As part of The Bin…
