Detection of single-degenerate massive binaries with Gaia: The impact of blue supergiants, triples, mass precision, and high-precision parallax requirements
S. Janssens, T. Shenar, H. Sana +1
Hundreds of black holes with massive main-sequence companions (OB+BHs) might be identified from Gaia astrometry with the Astrometric Mass-Ratio Function (AMRF). We investigate the…
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…
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…
