B-type Supergiants in the SMC: Chemical compositions and comparison of static and unified models
P. L. Dufton, R. S. I. Ryans, C. Trundle +4
High-resolution UCLES/AAT spectra are presented for nine B-type supergiants in the SMC, chosen on the basis that they may show varying amounts of nuclear-synthetically processed ma…
Chemical compositions of Four B-type Supergiants in the SMC Wing
J. -K. Lee, W. R. J. Rolleston, P. L. Dufton +1
High-resolution UCLES/AAT spectra of four B-type supergiants in the SMC South East Wing have been analysed using non-LTE model atmosphere techniques to determine their atmospheric…
The ultraviolet and optical spectra of luminous B-type stars in the Small Magellanic Cloud
C. J. Evans, D. J. Lennon, N. R. Walborn +2
We present ultraviolet spectra from the Space Telescope Imaging Spectrograph (STIS) of 12 early B-type stars in the Small Magellanic Cloud (SMC), comprising 9 supergiants and 3 gia…
The sub-millimetre evolution of V4334 Sgr (Sakurai's Object)
A. Evans, T. R. Geballe, V. H. Tyne +3
We report the results of monitoring of V4334 Sgr (Sakurai's Object) at 450 microns and 850 microns with SCUBA on the James Clerk Maxwell Telescope. The flux density at both wavelen…
Photometric Observations of the Type Ia SN 2002er in UGC 10743
G. Pignata, F. Patat, S. Benetti +20
Extensive light and colour curves for the Type Ia supernova SN 2002er are presented as part of the European Supernova Collaboration. We have collected UBVRI photometry from ten dif…
A Be star with a low nitrogen abundance in the SMC cluster NGC330
D. J. Lennon, J. -K. Lee, P. L. Dufton +1
High-resolution UVES/VLT spectra of B12, an extreme pole-on Be star in the SMC cluster NGC330, have been analysed using non-LTE model atmospheres to obtain its chemical composition…
