Stellar nucleosynthesis in the era of large surveys: S-process polluted binaries in GALAH DR4
A. Escorza, S. Vitali, D. Godoy-Rivera +11
Binary interactions during the AGB phase can lead to the formation of chemically peculiar stars with overabundances of s-process elements. Only a few hundreds of these stars have b…
Multiplicity of Massive stars in the Milky Way (M3W). I. Project description, UNWIND, application to GLS 11 448, and DIB catalog
J. MaÃz Apellániz, R. C. Gamen, G. Holgado +8
(ABRIDGED BUT NOT TOO FAR) Multiplicity is ubiquitous among massive stars and its understanding is constrained by the sample of well-determined orbits. The immediate goal of M3W is…
Magnetic field detections in massive systems at different stages of interaction
S. Hubrig, M. Abdul-Masih, S. P. Jarvinen +4
Despite the importance of magnetic fields in massive stars, their origin is widely debated and still not well understood. With the mounting evidence for the importance of studying…
Observations of massive contact binaries in the local universe
Michael Abdul-Masih
The contact phase represents a crossroad in the evolution of massive binary stars. Depending on the internal physics, the predicted end products can vary greatly including various…
Magnetic massive stars: confirming the merger scenario for the magnetic field generation
Swetlana Hubrig, Markus Schöller, Silva P. Järvinen +4
Magnetic fields are considered to be key components of massive stars, with a far-reaching impact on their evolution and ultimate fate. A magnetic mechanism was suggested for the co…
