The iron abundance of the Magellanic Bridge
P. L. Dufton, R. S. I. Ryans, H. M. A. Thompson +1
High-resolution HST ultra-violet spectra for five B-type stars in the Magellanic Bridge and in the Large and Small Magellanic Clouds have been analysed to estimate their iron abund…
Iron abundances from optical Fe III absorption lines in B-type stellar spectra
H. M. A. Thompson, F. P. Keenan, P. L. Dufton +3
The role of optical Fe III absorption lines in B-type stars as iron abundance diagnostics is considered. To date, ultraviolet Fe lines have been widely used in B-type stars, althou…
Iron abundances of B-type post-Asymptotic Giant Branch stars in globular clusters: Barnard 29 in M 13 and ROA 5701 in omega Cen
H. M. A. Thompson, F. P. Keenan, P. L. Dufton +4
High resolution optical and ultraviolet spectra of two B-type post-Asymptotic Giant Branch (post-AGB) stars in globular clusters, Barnard 29 in M 13 and ROA 5701 in omega Cen, have…
Observations towards early-type stars in the ESO-POP survey: II -- searches for intermediate and high velocity clouds
J. V. Smoker, I. Hunter, P. M. W. Kalberla +8
We present CaII K and TiII optical spectra of early-type stars taken mainly from the UVES Paranal Observatory Project, plus HI 21-cm spectra from the Vila-Elisa and Leiden-Dwingelo…
A non-LTE abundance analysis of the post-AGB star ROA 5701
H. M. A. Thompson, F. P. Keenan, P. L. Dufton +2
An analysis of high-resolution Anglo-Australian Telescope (AAT)/ University College London Echelle Spectrograph (UCLES) optical spectra for the ultraviolet (UV)-bright star ROA 570…
CaII K observations of QSOs in the line-of-sight to the Magellanic Bridge
J. V. Smoker, F. P. Keenan, H. M. A. Thompson +5
We describe medium-resolution spectroscopic observations taken with the ESO Multi-Mode Instrument in the CaII K line (3933.661 Angstroms) towards 7 QSOs located in the line-of-sigh…
