Microscopic surface structure of C/SiC composite mirrors for space cryogenic telescopes
Keigo Enya, Takao Nakagawa, Hidehiro Kaneda +3
We report on the microscopic surface structure of carbon-fiber-reinforced silicon carbide (C/SiC) composite mirrors that have been improved for the Space Infrared Telescope for Cos…
High Precision CTE-Measurement of SiC-100 for Cryogenic Space-Telescopes
K. Enya, N. Yamada, T. Onaka +7
We present the results of high precision measurements of the thermal expansion of the sintered SiC, SiC-100, intended for use in cryogenic space-telescopes, in which minimization o…
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…
