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…
Identifying quiescent compact objects in massive Galactic single-lined spectroscopic binaries
L. Mahy, H. Sana, T. Shenar +13
Aims. To search for these rare objects, we study 32 Galactic O-type stars that were reported as SB1s in the literature. In our sample we include Cyg X-1, which is known to host an…
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…
Detecting Stripped Stars While Searching for Quiescent Black Holes
J. Bodensteiner, M. Heida, M. Abdul-Masih +13
While the number of stellar-mass black holes detected in X-rays or as gravitational wave sources is steadily increasing, the known population remains orders of magnitude smaller th…
Modeling overcontact binaries, I. The effect of tidal deformation
M. Fabry, P. Marchant, H. Sana
In the realm of massive stars, strong binary interaction is commonplace. One extreme case are overcontact systems, which is expected to be part of the evolution of all stars evolvi…
Planet Hunters TESS IV: A massive, compact hierarchical triple star system TIC 470710327
Nora L. Eisner, Cole Johnston, Silvia Toonen +37
We report the discovery and analysis of a massive, compact, hierarchical triple system (TIC 470710327) initially identified by citizen scientists in data obtained by NASA's Transit…
