K., Wang, J., Wright, S.

Over the past three decades instruments on the ground and in space have discovered thousands of planets outside the solar system. These observations have given rise to an astonishingly detailed picture of the demographics of short-period planets, but

Properties of dust in the Galactic center region probed by AKARI far-infrared spectral mapping - detection of a dust feature

Autor: Kaneda, H., Yasuda, A., Onaka, T., Kawada, M., Murakami, N., Nakagawa, T., Okada, Y., Takahashi, H.

We investigate the properties of interstellar dust in the Galactic center region toward the Arches and Quintuplet clusters. With the Fourier Transform Spectrometer of the AKARI/Far-Infrared Surveyor, we performed the far-infrared (60 - 140 cm^-1) spe

An Eight-Octant Phase-Mask Coronagraph

Autor: Murakami, N., Uemura, R., Baba, N., Nishikawa, J., Tamura, M., Hashimoto, N., Abe, L.

We present numerical simulations and laboratory experiments on an eight-octant phase-mask (EOPM) coronagraph. The numerical simulations suggest that an achievable contrast for the EOPM coronagraph can be greatly improved as compared to that of a four
