Physics of Eclipsing Binaries. VI. Hot, compact stars
David Jones, Nicole Reindl, Kyle Conroy +9
Models of eclipsing binaries require the assignment of appropriate emergent intensities to the surface elements of the binary components. For distance-dependent modelling of flux-c…
Contact-binary evolution with energy transfer and saturated magnetic braking
Matthias Fabry, Andrej Prša
The evolution of low-mass contact binaries is influenced by angular-momentum loss, mass and energy transfer, and the nuclear evolution of the components. They have periods shorter…
The Nature of Unseen Companions in Massive Single-Line Spectroscopic Binaries
Hugues Sana, Michael Abdul-Masih, Gareth Banyard +14
Massive stars are predominantly found in binaries and higher order multiples. While the period and eccentricity distributions of OB stars are now well established across different…
Effects of limited core rejuvenation on the properties of massive contact binaries
Jelle Vandersnickt, Matthias Fabry
Context. Massive contact binaries are both stellar merger and gravitational wave progenitors, but their evolution is still uncertain. An open problem in the population synthesis of…
Modeling contact binaries, II. The effect of energy transfer
Matthias Fabry, Pablo Marchant, Norbert Langer +1
Context. It is common for massive stars to engage in binary interaction. In close binaries, the components can enter a contact phase, where both stars overflow their respective Roc…
Complex spectral variability and hints of a luminous companion in the Be star + black hole binary candidate ALS 8814
Kareem El-Badry, Matthias Fabry, Hugues Sana +2
The emission-line binary ALS 8814 was recently proposed as a Be star + black hole (BH) binary based on large-amplitude radial velocity (RV) variations of a Be star and non-detectio…
Modeling contact binaries, III. Properties of a population of close, massive binaries
Matthias Fabry, Pablo Marchant, Norbert Langer +1
Among massive stars, binary interaction is the rule rather than the exception. The closest binaries, those with periods of less than about 10 days, undergo mass transfer during cor…
An X-ray quiet black hole born with a negligible kick in a massive binary within the Large Magellanic Cloud
Tomer Shenar, Hugues Sana, Laurent Mahy +35
Stellar-mass black holes are the final remnants of stars born with more than 15 solar masses. Billions are expected to reside in the Local Group, yet only few are known, mostly det…
No signature of the orbital motion of a putative 70 solar mass black hole in LB-1
Michael Abdul-Masih, Gareth Banyard, Julia Bodensteiner +13
Liu et al. (2019) recently reported the detection of a 68 [+11/-13] solar mass (Msun) black hole (BH) paired with an 8.2 [+0.9/-1.2] Msun B-type sub-giant star in the 78.9-day spec…
Attributing the O'Connell effect in contact binaries to a cooling mass-transfer stream
Matthias Fabry, Andrej Prša
Contact binaries are very short-period systems that are continuously interacting by transferring mass and energy. Obtaining large, statistical samples of contact binaries from phot…
