Technetium and the third dredge up in AGB stars II. Bulge stars
Stefan Uttenthaler, Josef Hron, Thomas Lebzelter +3
We searched for Technetium (Tc) in a sample of bright oxygen-rich asymptotic giant branch (AGB) stars located in the outer galactic bulge. Tc is an unstable element synthesised via…
Optical spectroscopy of high proper motion stars: new M dwarfs within 10 pc and the closest pair of subdwarfs
C. Reyle, R. -D. Scholz, M. Schultheis +2
We present spectra of 59 nearby stars candidates, M dwarfs and white dwarfs, previously identified using high proper motion catalogues and the DENIS database. We review the existin…
ISO Mid-Infrared Spectroscopy of Galactic Bulge AGB Stars
Joris A. D. L. Blommaert, Martin A. T. Groenewegen, Koryo Okumura +8
To study the nature of Bulge AGB stars and in particular their circumstellar dust, we have analysed mid-infrared spectra obtained with the ISOCAM CVF spectrometer in three Bulge fi…
Near-IR spectroscopy of OH/IR stars in the Galactic Centre
E. Vanhollebeke, J. A. D. L. Blommaert, M. Schultheis +2
Context. Galactic Centre (GC) OH/IR stars can be, based on the expansion velocities of their circumstellar shells, divided into two groups which are kinematically different and the…
