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…
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…
CaII K interstellar observations towards early disc and halostars - Paper II; distances to IVCs and HVCs
J. V. Smoker, B. B. Lynn, W. R. J. Rolleston +8
We compare existing high spectral resolution (R=40,000) CaII K observations towards 88 mainly B-type stars, and new observations at R=10,000 towards 3 stars, with 21-cm HI emission…
Chemical abundances in the inner 5 kpc of the Galactic disk
S. J. Smartt, K. A. Venn, P. L. Dufton +3
High-resolution, high signal-to-noise spectral data are presented for four young B-type stars lying towards the Galactic Centre. Determination of their atmospheric parameters from…
PG 1002+506: a Be Star Apparently at Z Greater Than +10 kpc
F. A. Ringwald, W. R. J. Rolleston, R. A. Saffer +1
PG 1002+506 is found to be a Be star, one of two so far found by the Palomar-Green survey. Its spectrum is classified as a B5 +/- 1 Ve, with Teff = 14,900 +/- 1200, log g = 4.2 +/-…
