The 10 micron amorphous silicate feature of fractal aggregates and compact particles with complex shapes
M. Min, C. Dominik, J. W. Hovenier +2
We model the 10 micron absorption spectra of nonspherical particles composed of amorphous silicate. We consider two classes of particles, compact ones and fractal aggregates compos…
On the metallicity dependence of Wolf-Rayet winds
Jorick S. Vink, Alex de Koter
We have performed a pilot study of mass loss predictions for late-type Wolf-Rayet (WR) stars as a function of metal abundance, over a range between 10^{-5} < (Z/Zsun) < 10. We find…
Spectral analysis of early-type stars using a genetic algorithm based fitting method
M. R. Mokiem, A. de Koter, J. Puls +3
We present the first automated fitting method for the quantitative spectroscopy of O- and early B-type stars with stellar winds. The method combines the non-LTE stellar atmosphere…
The composition and size distribution of the dust in the coma of comet Hale-Bopp
M. Min, J. W. Hovenier, A. de Koter +2
We discuss the composition and size distribution of the dust in the coma of comet Hale-Bopp. We do this by fitting simultaneously the infrared emission spectrum measured by the inf…
The VLT-FLAMES Survey of Massive Stars: Observations in the Galactic Clusters NGC 3293, NGC 4755 and NGC 6611
C. J. Evans, S. J. Smartt, J. -K. Lee +23
We introduce a new survey of massive stars in the Galaxy and the Magellanic Clouds using the Fibre Large Array Multi-Element Spectrograph (FLAMES) instrument at the Very Large Tele…
A 10 micron spectroscopic survey of Herbig Ae star disks: grain growth and crystallization
R. van Boekel, M. Min, L. B. F. M. Waters +4
We present spectroscopic observations of a large sample of Herbig Ae stars in the 10 micrometer spectral region. We perform compositional fits of the spectra based on properties of…
