Infrared (IR) spectra provide a rich amount of information concerning chemical composition, lattice structure, size and shape of circumstellar dust. Accurate reference data are then required for the analysis of the various detected components. Thi...
Because interstellar dust is closely related to the evolution of matter in the galactic environment and many other astrophysical phenomena, the laboratory synthesis of interstellar dust analogs has received significant attention over the past deca...
The Infrared Space Observatory (ISO) detected several sharp infrared features around young stars, comets, and evolved stars. These sharp features were identified as Mg-rich crystalline silicates of forsterite and enstatite by comparison with spect...
We prepared sub-micron olivine (Fo(92)) particles of different shapes and different degrees of crystal lattice distortion, and studied both effects on the infrared absorption spectra experimentally. We found that the peak positions of the spectra ...
We carried out experiments of low-temperature infrared spectroscopy and transmission electron microscopy of enstatite (MgSiO(3)) synthesized by heating of amorphous magnesium silicate. There is a discrepancy between the infrared feature of enstati...
