Multi-dimensional, time-dependent approximate NLTE unified model atmospheres with winds for hot, massive stars
Dwaipayan Debnath, Jon O. Sundqvist, Nicolas Moens +3
Multi-dimensional unified model atmospheres with winds of massive stars have so far been studied under the assumption of equal flux, Planck, and energy weighted mean opacities, whi…
Simulations of massive star atmospheres and winds during giant eruptive and quiescent luminous blue variable phases
P. Schillemans, J. O. Sundqvist, D. Debnath +3
Mass loss from massive stars located in the part of the Hertzsprung-Russell diagram (HRD) where we find luminous blue variables (LBVs) is profoundly important for stellar evolution…
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…
Structure formation in O-type stars and Wolf-Rayet stars
C. Van der Sijpt, J. O. Sundqvist, D. Debnath +2
Turbulent small-scale structures in the envelopes and winds of massive stars have long been suggested as the cause for excessive line broadening that could not be explained by othe…
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…
