Spectroscopic fourth-order coronagraph for the characterization of terrestrial planets at small angular separations from host stars
Taro Matsuo, Satoshi Itoh, Yuji Ikeda
We propose a new approach for high-contrast imaging at the diffraction limit using segmented telescopes in a modest observation bandwidth. This concept, named "spectroscopic fourth…
Fourth-order Coronagraph for High-Contrast Imaging of Exoplanets with Off-axis Segmented Telescopes
Satoshi Itoh, Taro Matsuo
We propose a coronagraphic system with fourth-order null for off-axis segmented telescopes, which is sufficiently insensitive to the telescope pointing errors and finite angular di…
Pupil Masks for Spectrophotometry of Transiting Exoplanets
Satoshi Itoh, Taro Matsuo, Shohei Goda +2
Spectrophotometric stability, which is crucial in the spectral characterization of transiting exoplanets, is affected by photometric variations arising from field-stop loss in spac…
A New Concept for Spectro-photometry of Exoplanets with Space-based Telescopes
Taro Matsuo, Satoshi Itoh, Hiroshi Shibai +2
We propose a new concept for spectral characterization of transiting exoplanets with future space-based telescopes. This concept, called as densified pupil spectroscopy, allows us…
Observation of Rapid Change of Crystalline Structure during the Phase Transition of the Palladium-Hydrogen System
Akio Kawasaki, Satoshi Itoh, Kunihiro Shima +4
We performed an X-ray diffraction experiment while palladium bulk absorbed and desorbed hydrogen to investigate the behavior of the crystalline lattice during the phase transition…
Experimental observation of a first-order phase transition below the superconducting transition temperature in the multilayer cuprate superconductor HgBaCaCuO
Y. Tanaka, A. Iyo, S. Itoh +3
A first-order phase transition is found in the multilayer cuprate superconductor, HgBaCaCuO (Hg-1245), with a superconducting transition temperature of 108 K, under…
