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. Maíz 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…
Apsidal motion in massive binaries
Sophie Rosu
One of the most efficient and reliable observational technique allowing to probe the internal structure of a star is the determination of the apsidal motion in close eccentric bina…
Apsidal Motion in O-Star Binaries: GENEC rotating binary models put to the k2-test
Sophie Rosu, Luca Sciarini, Sylvia Ekström +1
Unveiling massive stars' internal structure and the physical origin and efficiency of the internal mixing processes? It is now possible using the apsidal motion rate in close eccen…
One century data of τ CMa: a (2+1)+1 system with a short-period overcontact binary and an eccentric intermediate orbit with probably no apsidal motion
Sophie Rosu, Jesús Maíz Apellániz, Luca Sciarini +4
τ Canis Majoris (CMa) is an intriguing system that has captured astronomers' attention for more than a century. The two main components Aa and Ab are two evolved O stars on a 350 y…
Phase-resolved XMM-Newton observations of the massive post-RLOF system HD 149404
G. Rauw, S. Lizin, S. Rosu +1
We investigated the X-ray emission of HD 149404, a 9.81-day period O-star binary in a post-Roche lobe overflow evolutionary stage. X-ray emission of O-star binaries consists of the…
Apsidal motion in massive eccentric binaries: The case of CPD-417742, and HD 152218 revisited
Sophie Rosu, Gregor Rauw, Yaël Nazé +2
This paper is part of a study of the apsidal motion in close eccentric massive binary systems, which aims to constrain the internal structure of the stars. We focus on the binary C…
Apsidal motion in the massive binary HD 152248 -- Constraining the internal structure of the stars
S. Rosu, A. Noels, M. -A. Dupret +3
Apsidal motion in massive eccentric binaries offers precious information about the internal structure of the stars. This is especially true for twin binaries consisting of two near…
Apsidal motion in the massive binary HD152248
S. Rosu, G. Rauw, K. E. Conroy +3
The eccentric massive binary HD152248 (also known as V1007 Sco), which hosts two O7.5 III-II(f) stars, is the most emblematic eclipsing O-star binary in the very young and rich ope…
Apsidal motion in the massive binary HD152218
G. Rauw, S. Rosu, A. Noels +5
Massive binary systems are important laboratories in which to probe the properties of massive stars and stellar physics in general. In this context, we analysed optical spectroscop…
