Viscous Instability Triggered by Layered Accretion in Protoplanetary Disks
Yasuhiro Hasegawa, Taku Takeuchi
Layered accretion is one of the inevitable ingredients in protoplanetary disks when disk turbulence is excited by magnetorotational instabilities (MRIs). In the accretion, disk sur…
Significant Gas-to-Dust Ratio Asymmetry and Variation in the Disk of HD 142527 and the Indication of Gas Depletion
Takayuki Muto, Takashi Tsukagoshi, Munetake Momose +14
We investigate the dust and gas distribution in the disk around HD 142527 based on ALMA observations of dust continuum, 13CO(3-2), and C18O(3-2) emission. The disk shows strong azi…
Detailed structure of the outer disk around HD 169142 with polarized light in H-band
Munetake Momose, Ayaka Morita, Misato Fukagawa +59
Coronagraphic imagery of the circumstellar disk around HD 169142 in H-band polarized intensity (PI) with Subaru/HiCIAO is presented. The emission scattered by dust particles at the…
Mass Estimates of a Giant Planet in a Protoplanetary Disk from the Gap Structures
Kazuhiro D. Kanagawa, Takayuki Muto, Hidekazu Tanaka +4
A giant planet embedded in a protoplanetary disk forms a gap. An analytic relationship among the gap depth, planet mass , disk aspect ratio , and viscosity has been…
Formation of a disc gap induced by a planet: Effect of the deviation from Keplerian disc rotation
Kazuhiro D. Kanagawa, Hidekazu Tanaka, Takayuki Muto +2
The gap formation induced by a giant planet is important in the evolution of the planet and the protoplanetary disc. We examine the gap formation by a planet with a new formulation…
