X-Shooting ULLYSES: Massive stars at low metallicity XV. On the metallicity dependence of B-supergiant mass-loss rates
O. Verhamme, J. O. Sundqvist, A. de Koter +21
Context. For stellar evolution models we rely on mass-loss rate prescriptions that show features that lack empirical confirmation, such as the bi-stability jump. This jump is an in…
The Tarantula massive binary monitoring VII. The nature of the eccentric O+BH binary candidate VFTS 812
K. Deshmukh, H. Sana, O. Verhamme +9
Massive O-type stars () with an X-ray quiet black hole (BH) companion represent a crucial stage in massive binary evolution leading to binary BH mergers. The p…
2D unified atmosphere and wind simulations for a grid of O-type stars
Nicolas Moens, Dwaipayan Debnath, Olivier Verhamme +4
The atmospheres of massive O-type stars (O stars) are dynamic, turbulent environments resulting from radiatively driven instabilities over the iron bump, located slightly beneath t…
Spectral synthesis of 3D unified model atmospheres with winds for O stars
L. Delbroek, J. O. Sundqvist, D. Debnath +5
Spectroscopic studies of massive and luminous O-type stellar atmospheres and winds have primarily been done by using 1D, spherically symmetric and stationary models. Both observati…
Improving 1D stellar atmosphere models with insights from multi-dimensional simulations II. 1D versus 3D hydrodynamically consistent model comparison for WR stars
G. González-Torà, A. A. C. Sander, N. Moens +8
Classical Wolf-Rayet (cWR) stars are evolved massive stars that have lost most of their H envelope and exhibit dense, extended atmospheres with strong, line-driven winds. Accuratel…
An on-the-fly line-driven-wind iterative mass-loss estimator (LIME) for hot, massive stars of arbitrary chemical compositions
J. O. Sundqvist, D. Debnath, F. Backs +7
Mass-loss rates from hot, massive stars are important for a range of astrophysical applications. We present \href{https://lime.ster.kuleuven.be/}{LIME}, a fast, efficient, and easy…
Improving 1D stellar atmosphere models with insights from multi-dimensional simulations I. 1D vs 2D stratifications and spectral comparison for O stars
G. González-Torà, A. A. C. Sander, J. O. Sundqvist +7
We compare current 1D and multi-dimensional atmosphere modelling approaches for massive stars to understand their strengths and shortcomings. We calculate averaged stratifications…
X-Shooting ULLYSES: Massive stars at low metallicity VI. Atmosphere and mass-loss properties of O-type giants in the Small Magellanic Cloud
Frank Backs, S. A. Brands, A. de Koter +21
Mass loss through a stellar wind is an important physical process that steers the evolution of massive stars and controls the properties of their end-of-life products, such as the…
X-Shooting ULLYSES: Massive Stars at low metallicity IX: Empirical constraints on mass-loss rates and clumping parameters for OB supergiants in the Large Magellanic Cloud
O. Verhamme, J. Sundqvist, A. de Koter +16
Context. Current implementations of mass loss for hot, massive stars in stellar evolution models include a sharp increase in mass loss when blue supergiants become cooler than Teff…
X-Shooting ULLYSES: Massive stars at low metallicity VII. Stellar and wind properties of B supergiants in the Small Magellanic Cloud
M. Bernini-Peron, A. A. C. Sander, V. Ramachandran +22
Context. B supergiants (BSGs) represent an important connection between the main sequence and more extreme evolutionary stages of massive stars. Additionally, lying toward the cool…
Jet formation in post-AGB binaries: Confronting cold magnetohydrodynamic disc wind wind models with observations
Toon De Prins, Hans Van Winckel, Jonathan Ferreira +4
Aims: We consider cold self-similar magnetohydrodynamic (MHD) disc wind solutions to describe jets that are launched from the circumcompanion accretion discs in post-AGB binaries.…
A dynamic view of V Hydrae. Monitoring of a spectroscopic-binary AGB star with an alkaline jet
L. Planquart, A. Jorissen, A. Escorza +2
The well studied carbon star V Hydrae is known to exhibit a complex asymmetric environment made of a dense equatorial wind and high-velocity outflows, hinting at its transition fro…

Using the medium resolution spectrograph X-shooter, spectra of 235 OB and Wolf-Rayet (WR) stars in sub-solar metallicity environments have been secured. [...]This second paper focu…
2D unified atmosphere and wind simulations of O-type stars
D. Debnath, J. O. Sundqvist, N. Moens +3
Massive and luminous O-star atmospheres with winds have been studied primarily using one-dimensional (1D), spherically symmetric, and stationary models. However, observations and t…
Magnetically driven winds from accretion disks in post-asymptotic giant branch binaries
Olivier Verhamme, Jacques Kluska, Jonathan Ferreira +4
Context. Jets are commonly detected in post-asymptotic giant branch (post-AGB) binaries and originate from an accretion process onto the companion of the post-AGB primary. These je…
