Quantitative studies of the optical and UV spectra of Galactic early B supergiants I. Fundamental parameters
Samantha C. Searle, Raman K. Prinja, Derck Massa +1
We undertake an optical and ultraviolet spectroscopic analysis of a sample of 20 Galactic B0 - B5 supergiants of luminosity classes Ia, Ib, Iab and II. Fundamental stellar paramete…
Structure and clumping in the fast wind of NGC6543
R. K. Prinja, S. E. Hodges, D. L. Massa +2
Far-UV spectroscopy from the FUSE satellite is analysed to uniquely probe spatial structure and clumping in the fast wind of the central star of the H-rich planetary nebula NGC6543…
The effects of clumping on wind line variability
D. Massa, R. K. Prinja, A. W. Fullerton
We review the effects of clumping on the profiles of resonance doublets. By allowing the ratio of the doublet oscillator strenghts to be a free parameter, we demonstrate that doubl…
The superimposed photospheric and stellar wind variability of the O-type supergiant alpha Cam
R. K. Prinja, N. Markova, S. Scuderi +1
(Abridged) We provide empirical constraints on the different physical components that can act to yield temporal variability in predominantly or partially wind-formed optical lines…
