First spatially resolved Na I and He I transitions towards an MYSO. Finding new tracers for the gaseous star/disc interface
Evgenia Koumpia, M. Koutoulaki, W. -J. de Wit +4
With steady observational advances, the formation of massive stars is being understood in more detail. Numerical models are converging on a scenario where accretion discs play a ke…
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…
HR 6819 is a binary system with no black hole -- revisiting the source with infrared interferometry and optical integral field spectroscopy
A. J. Frost, J. Bodensteiner, Th. Rivinius +16
Two scenarios have been proposed to match the existing observational constraints of the object HR 6819. The system could consist of a close inner B-type giant plus a black hole (BH…
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…
Tying the geometrical traits of massive young stellar objects and their discs to a potential evolutionary sequence using infrared observations
A. J. Frost, R. D. Oudmaijer, S. L. Lumsden +1
Young massive stars influence their surroundings from local to galactic scales, but the observational challenges associated with their distance and embedded nature has, until the r…
The first interferometric survey in the K-band of massive YSOs. On the hot dust, ionised gas, and binarity at au scales
E. Koumpia, W. -J. de Wit, R. D. Oudmaijer +8
Circumstellar discs are essential for high mass star formation, while multiplicity, in particular binarity, appears to be an inevitable outcome since the vast majority of massive s…
