Two-Component Secular Gravitational Instability in a Protoplanetary Disk: A Possible Mechanism for Creating Ring-Like Structures
Sanemichi Z. Takahashi, Shu-ichiro Inutsuka
The instability in protoplanetary disks due to gas-dust friction and self-gravity of gas and dust is investigated by linear analysis. In the case where the dust to gas ratio is enh…
Local Enhancement of Surface Density in the Protoplanetary Ring Surrounding HD 142527
Misato Fukagawa, Takashi Tsukagoshi, Munetake Momose +15
We report ALMA observations of dust continuum, 13CO J=3--2, and C18O J=3--2 line emission toward a gapped protoplanetary disk around HD 142527. The outer horseshoe-shaped disk show…
A Semi-Analytical Description for the Formation and Gravitational Evolution of Protoplanetary Disks
Sanemichi Z. Takahashi, Shu-ichiro Inutsuka, Masahiro N. Machida
We investigate the formation process of self-gravitating protoplanetary disks in unmagnetized molecular clouds. The angular momentum is redistributed by the action of gravitational…
