The IACOB project XIX. Revisiting massive-star evolution with empirical TAMS constraints: updated models, overshoot calibration, and the population of blue supergiants
Luca Sciarini, Abel de Burgos, Sophie Rosu +3
Massive stars play a fundamental role in the evolution of the Universe. Yet, several physical processes governing their evolution remain poorly constrained. Notably, the main-seque…
The outer rings of SN 1987A from year 1994 to 2024: morphology, light curves, and optical to mid-infrared spectra
Sophie Rosu, Elko Gerville-Reache, Steven Thomas +14
The outer rings (ORs) of Supernova (SN) 1987A were ejected ~20000 years before the explosion. Their characterisation is crucial for constraining the properties of the progenitor of…
The Beauty of k2: Probing Stellar Interiors Using Apsidal Motion. I. The Benchmark Massive Binary HD 152248
Sophie Rosu, Luca Sciarini, Sylvia Ekström +4
Over the last decades, several independent studies have shown the need for large convective boundary mixing (CBM) and convective core sizes in massive stars to reproduce a variety…
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…
Detached eclipsing binary star science in the 2040s
Pierre F. L. Maxted, Dominic M. Bowman, Thomas G. Wilson +7
Detached eclipsing binary stars (DEBS) are currently the best source of accurate and precise fundamental stellar parameters. This makes DEBS crucial targets for constraining the im…
Chemical evolution of close massive binaries -- tidally-enhanced or tidally-suppressed mixing?
Luca Sciarini, Sophie Rosu, Sylvia Ekström +3
One of the largest source of uncertainties in the predictions of stellar models comes from the internal transport mechanisms. In close massive binaries, previous theoretical studie…
