B-type supergiants in the SMC: Rotational velocities and implications for evolutionary models
P. L. Dufton, R. S. I. Ryans, S. Simon-Diaz +2
High-resolution spectra for 24 SMC and Galactic B-type supergiants have been analysed to estimate the contributions of both macroturbulence and rotation to the broadening of their…
The VLT-FLAMES Survey of Massive Stars: Observations in the Galactic Clusters NGC 3293, NGC 4755 and NGC 6611
C. J. Evans, S. J. Smartt, J. -K. Lee +23
We introduce a new survey of massive stars in the Galaxy and the Magellanic Clouds using the Fibre Large Array Multi-Element Spectrograph (FLAMES) instrument at the Very Large Tele…
Fe XI emission lines in a high resolution extreme ultraviolet spectrum obtained by SERTS
F. P. Keenan, K. M. Aggarwal, R. S. I. Ryans +5
New calculations of radiative rates and electron impact excitation cross sections for Fe XI are used to derive emission line intensity ratios involving 3s^23p^4 - 3s^23p^33d transi…
A non-LTE analysis of the spectra of two narrow lined main sequence stars in the SMC
I. Hunter, P. L. Dufton, R. S. I. Ryans +4
An analysis of high-resolution VLT/UVES spectra of two B-type main sequence stars, NGC 346-11 and AV 304, in the Small Magellanic Cloud (SMC), has been undertaken, using the non-LT…
