Metallicity effects in the spectral classification of O-type stars. Theoretical consideration
N. Markova, L. Bianchi, B. Efremova +1
Based on an exteded grid of NLTE, line blanketed model atmospheres with stellar winds as calculated by means of FASTWIND, we have investigated the change in the strengths of strate…
Wind structure of late B supergiants I. Multi-line analyses of near-surface and wind structure in HD 199 478 (B8 Iae)
N. Markova, R. Prinja, H. Markov +4
We provide a quantitative analysis of time-variable phenomena in the photospheric, near-star, and outflow regions of the late-B supergiant (SG) HD 199478. The analysis is based pri…
Bright OB stars in the Galaxy IV. Stellar and wind parameters of early to late B supergiants
N. Markova, J. Puls
We apply the NLTE atmosphere code FASTWIND to perform a spectroscopic study of a small sample of Galactic B-supergiants from B0 to B9. By means of the resulting data and incorporat…
Stellar winds from massive stars - What are the REAL mass-loss rates?
J. Puls, N. Markova, S. Scuderi
We discuss recent evidence that currently accepted mass-loss rates may need to be revised downwards, as a consequence of previously neglected ``clumping'' of the wind. New results…
Bright OB stars in the Galaxy - III. Constraints on the radial stratification of the clumping factor in hot star winds from a combined Halpha, IR and radio analysis
J. Puls, N. Markova, S. Scuderi +4
Recent results strongly challenge the canonical picture of massive star winds: various evidence indicates that currently accepted mass-loss rates, Mdot, may need to be revised down…
