A CH3CN and HCO+ survey towards southern methanol masers associated with star formation
C. R. Purcell, R. Balasubramanyam, M. G. Burton +32
We present the initial results of a 3-mm spectral line survey towards 83 methanol maser selected massive star-forming regions. Here we report observations of the J=5-4 and 6-5 rota…
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…
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…
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…
