Resolved 24.5 micron emission from massive young stellar objects
W. J. de Wit, M. G. Hoare, T. Fujiyoshi +8
Massive young stellar objects (MYSO) are surrounded by massive dusty envelopes. Our aim is to establish their density structure on scales of ~1000 AU, i.e. a factor 10 increase in…
A red supergiant nebula at 25 micron: arcsecond scale mass-loss asymmetries of mu Cep
W. J. de Wit, R. D. Oudmaijer, T. Fujiyoshi +8
We present diffraction limited (0.6") 24.5micron Subaru/COMICS images of the red supergiant mu Cep. We report the detection of a circumstellar nebula, that was not detected at shor…
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…
The Asymmetric Thermal Emission of Protoplanetary Disk Surrounding HD 142527 Seen by Subaru/COMICS
Hideaki Fujiwara, Mitsuhiko Honda, Hirokazu Kataza +8
Mid-infrared (MIR) images of the Herbig Ae star HD 142527 were obtained at 18.8 and 24.5 micron with the Subaru/COMICS. Bright extended arc-like emission (outer disk) is recognized…
Ionization of Polycyclic Aromatic Hydrocarbon Molecules around the Herbig Ae/Be environment
Itsuki Sakon, Yoshiko K. Okamoto, Hirokazu Kataza +3
We present the results of mid-infrared N-band spectroscopy of the Herbig Ae/Be system MWC1080 using the Cooled Mid-Infrared Camera and Spectrometer (COMICS) on board the 8m Subaru…
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…
