Hidden metallic iron in amorphous silicate dust? Insights from condensation experiments and mid-infrared spectroscopy
Hanako Enomoto, Aki Takigawa, Hiroki Chihara +1
Amorphous silicate dust is a major component in the interstellar and circumstellar dust formed in the outflow of asymptotic giant branch (AGB) stars. Although iron depletion is obs…
Radiative equilibrium estimates of dust temperature and mass in high-redshift galaxies
Akio K. Inoue, Takuya Hashimoto, Hiroki Chihara +1
Estimating the temperature and mass of dust in high- galaxies is essential for discussions of the origin of dust in the early Universe. However, this suffers from limited sampli…
Mid-infrared spectroscopy of zodiacal emission with AKARI/IRC
Aoi Takahashi, Takafumi Ootsubo, Hideo Matsuhara +3
Interplanetary dust (IPD) is thought to be recently supplied from asteroids and comets. Grain properties of the IPD can give us the information about the environment in the proto-s…
Absorption and scattering by interstellar dust in the silicon K-edge of GX 5-1
S. T. Zeegers, E. Costantini, C. P. de Vries +6
We study the absorption and scattering of X-ray radiation by interstellar dust particles, which allows us to access the physical and chemical properties of dust. The interstellar d…
Photo-Luminescence and Possible Forsterite nanoparticles Model of Extended Red Emission
K. Koike, H. Chihara, C. Koike +4
Possible forsterite nanoparticle model of the Extended Red Emission(ERE) is proposed on the basis of photo-luminescence of forsterite after gamma-ray and neutron irradiation. Forst…
PAHs and crystalline silicates in the post-AGB star IRAS 16279-4757
M. Matsuura, A. A. Zijlstra, F. J. Molster +7
IRAS 16279-4757 belongs to a group of post-AGB stars showing both PAH bands and crystalline silicates. We present mid-infrared images, that resolve the object for the first time. T…
