Laboratory demonstration of a cryogenic deformable mirror for wavefront correction of space-borne infrared telescopes
Aoi Takahashi, Keigo Enya, Kanae Haze +9
This paper demonstrates a cryogenic deformable mirror (DM) with 1,020 actuators based on micro-electrical mechanical systems (MEMS) technology. Cryogenic space-borne infrared teles…
Experimental demonstration of binary shaped pupil mask coronagraphs for telescopes with obscured pupils
Kanae Haze, Keigo Enya, Lyu Abe +3
We present the fabrication and experimental demonstration of three free-standing binary shaped pupil mask coronagraphs, which are applicable for telescopes with partially obscured…
Coronagraphic demonstration experiment using aluminum mirrors for space infrared astronomical observations
Shinji Oseki, Shinki Oyabu, Daisuke Ishihara +7
For future space infrared astronomical coronagraphy, we perform experimental studies on the application of aluminum mirrors to a coronagraph. Cooled reflective optics is required f…
Comparative study of manufacturing techniques for coronagraphic binary pupil masks: masks on substrates and free-standing masks
Keigo Enya, Kanae Haze, Takayuki Kotani +1
We present a comparative study of the manufacture of binary pupil masks for coronagraphic observations of exoplanets. A checkerboard mask design, a type of binary pupil mask design…
Development of binary shaped pupil mask coronagraph for the observation of exoplanets
Kanae Haze
Direct observation of extra-solar planets (exoplanets) is essential to understand how planetary systems were born, how they evolve, and ultimately, to identify biological signature…
High contrast experiment of an AO-free coronagraph with a checkerboard pupil mask
K. Enya, L. Abe, S. Tanaka +4
A high contrast coronagraph is expected to provide one of the promising ways to directly observe extra-solar planets. We present the newest results of our laboratory experiment inv…
The SPICA coronagraphic instrument (SCI) for the study of exoplanets
K. Enya, T. Kotani, K. Haze +39
We present the SPICA Coronagraphic Instrument (SCI), which has been designed for a concentrated study of extra-solar planets (exoplanets). SPICA mission provides us with a unique o…
Multi-Color Coronagraph Experiment in a Vacuum Testbed with a Binary Shaped Pupil Mask
Kanae Haze, Keigo Enya, Lyu Abe +4
We conducted a number of multi-band coronagraph experiments using a vacuum chamber and a binary-shaped pupil mask which in principle should work at all wavelengths, in the context…
Detection of an H-alpha Emission Line on a Quasar, RX J1759.4+6638, at z=4.3 with AKARI
Shinki Oyabu, Takehiko Wada, Youichi Ohyama +18
We report the detection of an H-alpha emission line in the low resolution spectrum of a quasar, RX J1759.4+6638, at a redshift of 4.3 with the InfraRed Camera (IRC) onboard the AKA…
