The IACOB project: XVII. Nitrogen abundances in Galactic O-type stars: further hints for separating binary-interaction products from effectively single stars
C. Martínez-Sebastián, G. Holgado, S. Simón-Díaz +2
Context. Growing evidence is revealing the crucial role of binarity in massive star evolution. This affects evolution models and demands a refinement of the available observational…
The IACOB project: XVI. Surface helium abundances in Galactic O-type stars: indications for identifying binary interaction products
S. Simón-Díaz, G. Holgado, C. Martínez-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…
Toward early-type eclipsing binaries as extragalactic milestones: IV. Physical properties of three detached O/B-type systems in the LMC
Mónica Taormina, G. Pietrzyński, R. -P. Kudritzki +10
We present a complete set of physical parameters for three early-type eclipsing binary systems in the Large Magellanic Cloud (LMC): OGLE LMC-ECL-17660, OGLE LMC-ECL-18794, and HV 2…
The IACOB project XIII. Helium enrichment in O-type stars as a tracer of past binary interaction
C. Martínez-Sebastián, S. Simón-Díaz, H. Jin +4
There is increasing evidence that single-star evolutionary models are inadequate to reproduce all observational properties of massive stars. Binary interaction has emerged as a key…
The effects of surface fossil magnetic fields on massive star evolution: V. Models at low metallicity
Z. Keszthelyi, J. Puls, G. Chiaki +4
At metallicities lower than that of the Small Magellanic Cloud, it remains essentially unexplored how fossil magnetic fields, forming large-scale magnetospheres, could affect the e…
Towards early-type eclipsing binaries as extragalactic milestones: III. Physical properties of the O-type eclipsing binary OGLE LMC-ECL-21568 in a quadruple system
Mónica Taormina, R. -P. Kudritzki, B. Pilecki +8
We present the results from a complex study of an eclipsing O-type binary (Aa+Ab) with the orbital period days, that forms part of a higher-order multiple system…
