Properties of polycyclic aromatic hydrocarbons in local elliptical galaxies revealed by the Infrared Spectrograph on Spitzer
H. Kaneda, T. Onaka, I. Sakon +3
We performed mid-infrared spectroscopic observations of 18 local dusty elliptical galaxies by using the Infrared Spectrograph (IRS) on board Spitzer. We have significantly detected…
Si and Fe depletion in Galactic star-forming regions observed by the Spitzer Space Telescope
Yoko Okada, Takashi Onaka, Takashi Miyata +4
We report the results of the mid-infrared spectroscopy of 14 Galactic star-forming regions with the high-resolution modules of the Infrared Spectrograph (IRS) on board the Spitzer…
Large Silicon Abundance in Photodissociation Regions
Yoko Okada, Takashi Onaka, Takao Nakagawa +3
We have made one-dimensional raster-scan observations of the rho Oph and sigma Sco star-forming regions with two spectrometers (SWS and LWS) on board the ISO. In the rho Oph region…
Crystalline Silicate Feature of the Vega-like star HD145263
Mitsuhiko Honda, Hirokazu Kataza, Yoshiko K. Okamoto +8
We have observed the 8-13 m spectrum (R250) of the Vega-like star candidate HD145263 using Subaru/COMICS. The spectrum of HD145263 shows the broad trapezoidal silicate fea…
Mid- to Far-Infrared spectroscopy of Sharpless 171
Y. Okada, T. Onaka, H. Shibai +1
We have collected one-dimensional raster-scan observations of the active star-forming region Sharpless 171 (S171), a typical HII region-molecular cloud complex, with the three spec…
