Probing Thin Winds in Massive OB Stars of the SMC with JWST/NIRSPEC Br-alpha Spectroscopy
Miriam Garcia, Alexander W. Fullerton, Francisco Najarro +12
Mass loss is a key physical process in the evolution of massive stars, the impact of which propagates into galactic evolution, population synthesis models, the interpretation of hi…
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…
Suppression of photospheric velocity fluctuations in strongly magnetic O-stars in radiation-magnetohydrodynamic simulations
A. ud-Doula, J. O. Sundqvist, N. Narechania +3
O-stars generally show clear signs of strong line-broadening (in addition to rotational broadening) in their photospheric absorption lines (typically referred to as 'macroturbulenc…
Empirical mass-loss rates and clumping properties of O-type stars in the LMC
C. Hawcroft, L. Mahy, H. Sana +6
We constrain wind parameters of a sample of 18 O-type stars in the LMC, through analysis with stellar atmosphere and wind models including the effects of optically thick clumping.…
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…
