Pollution versus diffusion: Abundance patterns of blue horizontal branch stars in globular clusters NGC6388, NGC6397, and NGC6752
Sabine Moehler
Context: The metal-rich bulge globular cluster NGC6388 shows a blue horizontal branch (HB). Helium (He) enrichment, which is correlated with changes in other light elements, might…
Progress on FORS-Up: the first instrument using ELT technologies
H. M. J. Boffin, V. Baldini, S. Bertocco +21
ESO is in the process of upgrading one of the two FORS (FOcal Reducer/low dispersion Spectrograph) instruments - a multi-mode (imaging, polarimetry, long-slit, and multi-object spe…
Flux calibration of medium-resolution spectra from 300 nm to 2500 nm: Model reference spectra and telluric correction
S. Moehler, A. Modigliani, W. Freudling +8
While the near-infrared wavelength regime is becoming more and more important for astrophysics there is a marked lack of spectrophotometric standard star data that would allow the…
Hot horizontal branch stars in NGC 288 - effects of diffusion and stratification on their atmospheric parameters
S. Moehler, S. Dreizler, F. LeBlanc +5
NGC288 is a globular cluster with a well-developed blue horizontal branch covering the u-jump that indicates the onset of diffusion. It is therefore well suited to study the effect…
Spectroscopy of horizontal branch stars in Omega Centauri
C. Moni Bidin, S. Villanova, G. Piotto +3
We analyze the reddening, surface helium abundance and mass of 115 horizontal branch (HB) and blue hook (BH) stars in OmegaCentauri, spanning the HB from the blue edge of the insta…
Good News for MOS, MXU & Co. - The New Spectroscopic Pipeline for the FORSes
S. Moehler
Since October 1, 2006, spectroscopic data from the two FORS instruments have been reduced with a new pipeline, which is based on a bottom-up calibration approach. I give a short de…
