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…
Mid-Infrared Instrumentation for the European Extremely Large Telescope
S. Kendrew, B. Brandl, R. Lenzen +5
MIDIR is the proposed thermal/mid-IR imager and spectrograph for the European Extremely Large Telescope (E-ELT). It will cover the wavelength range of 3 to at least 20 microns. Des…
VISIR/VLT mid-infrared imaging of Seyfert nuclei: Nuclear dust emission and the Seyfert-2 dichotomy
Martin Haas, Ralf Siebenmorgen, Eric Pantin +5
Half of the Seyfert-2 galaxies escaped detection of broad lines in their polarised spectra observed so far. Some authors have suspected that these non-HBLRs contain real Sy2 nuclei…
Spectral type dependent rotational braking and strong magnetic flux in three components of the late-M multiple system LHS 1070
Ansgar Reiners, Andreas Seifahrt, Hans Ulrich Käufl +2
We show individual high resolution spectra of components A, B, and C of the nearby late-M type multiple system LHS 1070. Component A is a mid-M star, B and C are known to have mass…
A First Study of Giant Stars in the Galactic Bulge based on Crires spectra
N. Ryde, B. Edvardsson, B. Gustafsson +1
We present our on-going work on the determination of elemental abundances of giants in the Galactic Bulge by means of infrared spectroscopy. We show a preliminarily reduced spectru…
TIMMI2 and VLT-ISAAC Spectroscopy of Circumstellar Dust Disks - A Spatially Resolved 3.3 micron PAH Feature Around HD 100546
V. C. Geers, J. -C. Augereau, K. M. Pontoppidan +4
We present preliminary results of spectroscopic data obtained with the La Silla 3.6m TIMMI2 and the VLT-ISAAC instruments. We have obtained 23 TIMMI2 N-band and 18 Q-band spectra f…
