Low temperature Rosseland opacities with varied abundances of carbon and nitrogen
Michael T. Lederer, Bernhard Aringer
We attempt to produce low temperature opacity data incorporating the effects of varied abundances of the elements carbon and nitrogen. For our temperature range of interest, molecu…
VSI: the VLTI spectro-imager
F. Malbet, D. Buscher, G. Weigelt +51
The VLTI Spectro Imager (VSI) was proposed as a second-generation instrument of the Very Large Telescope Interferometer providing the ESO community with spectrally-resolved, near-i…
The fluorine abundance in a Galactic Bulge AGB star measured from CRIRES spectra
Stefan Uttenthaler, Thomas Lebzelter, Bernhard Aringer +3
We present measurements of the fluorine abundance in a Galactic Bulge Asymptotic Giant Branch (AGB) star. The measurements were performed using high resolution K-band spectra obtai…
Milli-arcsecond astrophysics with VSI, the VLTI spectro-imager in the ELT era
F. Malbet, D. Buscher, G. Weigelt +49
Nowadays, compact sources like surfaces of nearby stars, circumstellar environments of stars from early stages to the most evolved ones and surroundings of active galactic nuclei c…
Low temperature mean opacities for the carbon-rich regime
Michael T. Lederer, Bernhard Aringer
Asymptotic Giant Branch (AGB) stars undergo a change in their chemical composition during their evolution. This in turn leads to an alteration of the radiative opacities, especiall…
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…
