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…
Primordial porous structure of chondrite parent bodies due to self-gravity
Tomomi Omura, Akiko M. Nakamura
The porosity of an asteroid is important when studying the evolution of our solar system through small bodies and for planning mitigation strategies to avoid disasters due to aster…
Centroid migration on an impacted granular slope due to asymmetric ejecta deposition and landsliding
Tomomi Omura, Shinta Takizawa, Hiroaki Katsuragi
For a fundamental understanding of terrain relaxation occurring on sloped surfaces of terrestrial bodies, we analyze the crater shape produced by an impact on an inclined granular…
Ring formation by coagulation of dust aggregates in early phase of disk evolution around a protostar
Satoshi Ohashi, Hiroshi Kobayashi, Riouhei Nakatani +6
Ring structures are observed by (sub-)millimeter dust continuum emission in various circumstellar disks from early stages of Class 0 and I to late stage of Class II young stellar o…
Mid-infrared spectroscopy of zodiacal emission with AKARI/IRC
Aoi Takahashi, Takafumi Ootsubo, Hideo Matsuhara +3
Interplanetary dust (IPD) is thought to be recently supplied from asteroids and comets. Grain properties of the IPD can give us the information about the environment in the proto-s…
Two Different Grain Size Distributions within the Protoplanetary Disk around HD 142527 Revealed by ALMA Polarization Observation
Satoshi Ohashi, Akimasa Kataoka, Hiroshi Nagai +7
The origin of polarized emission from protoplanetary disks is uncertain. Three mechanisms have been proposed for such polarized emission: grain alignment with magnetic fields, grai…
