ASTROPHYSICAL JOURNAL LETTERS 749(2) 2012年4月

We report an intriguing debris disk toward the F3V star HD 15407A in which an extremely large amount of warm fine dust (similar to 10(-7)M(circle dot)) is detected. The dust temperature is derived as similar to 500-600 K and the location of the de...

GROUND-BASED AND AIRBORNE INSTRUMENTATION FOR ASTRONOMY IV 8446 2012年

We have evaluated on-sky performances of a mid-infrared camera MAX38 (Mid-infrared Astronomical eXploerer) on the miniTAO 1-meter telescope. A Strehl ratio at the N-band is estimated to be 0.7-0.8, and it reaches to 0.9 at the 37.7 micron, indicat...

SPACE TELESCOPES AND INSTRUMENTATION 2012: OPTICAL, INFRARED, AND MILLIMETER WAVE 8442 2012年

We present the Prototype-testbed for Infrared Optics and Coronagraphs (PINOCO) which is a large, multi-purpose cryogenic chamber. At present, the priority for PINOCO is to evaluate binary pupil mask coronagraphs in the mid-infrared wavelength regi...

GROUND-BASED AND AIRBORNE INSTRUMENTATION FOR ASTRONOMY IV 8446 2012年

TAO (The University of Tokyo Atacama Observatory) is planned to be constructed at the summit of Co. Chajnantor (5640 m altitude) in Chile. MIMIZUKU (Mid-Infrared Multi-field Imager for gaZing at the UnKnown Universe) is a mid-infrared imager (Fiel...
