Mid-IR period-magnitude relations for AGB stars
I. S. Glass, M. Schultheis, J. A. D. L. Blommaert +3
Asymptotic Giant Branch variables are found to obey period-luminosity relations in the mid-IR similar to those seen at K_S (2.14 microns), even at 24 microns where emission from ci…
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…
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…
The wave nature of biomolecules and fluorofullerenes
Lucia Hackermueller, Stefan Uttenthaler, Klaus Hornberger +4
We demonstrate quantum interference for tetraphenylporphyrin, the first biomolecule exhibiting wave nature, and for the fluorofullerene C60F48 using a near-field Talbot-Lau interfe…
Collisional decoherence observed in matter wave interferometry
Klaus Hornberger, Stefan Uttenthaler, Bjoern Brezger +3
We study the loss of spatial coherence in the extended wave function of fullerenes due to collisions with background gases. From the gradual suppression of quantum interference wit…
