Pixie Dust: The Silicate Features in the Diffuse Interstellar Medium
J. E. Chiar, A. G. G. M. Tielens
We have analyzed the 9.7 and ``18'' micron interstellar silicate absorption features along the line of sight toward four heavily extincted galactic WC-type Wolf-Rayet (WR) stars. W…

The Detection of Silicate Emission from Quasars at 10 and 18 Microns
Lei Hao, H. W. W. Spoon, G. C. Sloan +8
We report the spectroscopic detection of silicate emission at 10 and 18 microns in five PG quasars, the first detection of these two features in galaxies outside the Local Group. T…

Molecular hydrogen formation on grain surfaces
S. Cazaux, P. Caselli, A. G. G. M. Tielens +2
We reconsider H2 formation on grain surfaces. We develop a rate equation model which takes into account the presence of both physisorbed and chemisorbed sites on the surface, inclu…
