The water-ice feature in near-infrared disk-scattered light around HD 142527: Micron-sized icy grains lifted up to the disk surface?

Ryo Tazaki, Koji Murakawa, Takayuki Muto +2

We study the m scattering feature of water ice detected in the outer disk of HD 142527 by performing radiative transfer simulations. We show that an ice mass abundance at the…

On the crystallinity of silicate dust in evolving protoplanetary disks due to magnetically driven disk winds

Sota Arakawa, Yuji Matsumoto, Mitsuhiko Honda

We present a novel mechanism for the outward transport of crystalline dust particles: the outward radial drift of pebbles. The dust ring structure is frequently observed in protopl…

The formation of planetary systems with SPICA

I. Kamp, M. Honda, H. Nomura +38

In this era of spatially resolved observations of planet forming disks with ALMA and large ground-based telescopes such as the VLT, Keck and Subaru, we still lack statistically rel…

Scattering polarization of 3-m water-ice feature by large icy grains

Ryo Tazaki, Koji Murakawa, Takayuki Muto +2

Water ice has a strong spectral feature at a wavelength of approximately m, which plays a vital role in our understanding of the icy universe. In this study, we investigate th…

Unidentified Infrared Emission Features in Mid-infrared Spectrum of Comet 21P/Giacobini-Zinner

Takafumi Ootsubo, Hideyo Kawakita, Yoshiharu Shinnaka +2

Comet 21P/Giacobini-Zinner (hereafter, comet 21P/G-Z) is a Jupiter-family comet and a parent comet of the October Draconids meteor shower. If meteoroids originating from a Jupiter-…

Mid-infrared spectroscopic observations of comet 17P/Holmes immediately after its great outburst in October 2007

Yoshiharu Shinnaka, Takafumi Ootsubo, Hideyo Kawakita +3

Dust grains of crystalline silicate, which are rarely presented in interstellar space, were found in cometary nuclei. These crystalline silicates are thought to have formed by anne…
