Beyond the model: scaling the wind-driven accretion rate in protoplanetary disks using systematic non-ideal magnetohydrodynamical simulations
Haruhi Enomoto, Shoji Mori, Satoshi Okuzumi
Magnetically driven mass accretion plays a key role in protoplanetary disk evolution and planet formation. However, the alpha prescription remains phenomenological, and how the acc…
Radiative Nonideal MHD Simulations of Inner Protoplanetary Disks: Temperature Structures, Asymmetric Winds, and Episodic Surface Accretion
Shoji Mori, Xue-Ning Bai, Kengo Tomida
We perform two-dimensional global magnetohydrodynamic (MHD) simulations including the full nonideal MHD effects (Ohmic diffusion, Hall effect, and ambipolar diffusion) and approxim…
Long-term evolution of the temperature structure in magnetized protoplanetary disks and its implication for the dichotomy of planetary composition
Shoji Mori, Masanobu Kunitomo, Masahiro Ogihara
The thermal structure and evolution of protoplanetary disks play a crucial role in planet formation. In addition to stellar irradiation, accretion heating is also thought to signif…
Solving for the 2D Water Snowline with Hydrodynamic Simulations. Emergence of gas outflow, water cycle and temperature plateau
Yu Wang, Chris W. Ormel, Shoji Mori +1
In protoplanetary disks, the water snowline marks the location where ice-rich pebbles sublimate, releasing silicate grains and water vapor. These processes can trigger pile-ups of…

Shigehisa Takakuwa, Kazuya Saigo, Miyu Kido +22
We performed radiative transfer calculations and observing simulations to reproduce the 1.3-mm dust-continuum and CO (2-1) images in the Class I protostar R CrA IRS7B-a, obs…
Synthetic Observations of the Infalling Rotating Envelope: Links between the Physical Structure and Observational Features
Shoji Mori, Yuri Aikawa, Yoko Oya +2
We performed synthetic observations of the Ulrich, Cassen, and Moosman (UCM) model to understand the relation between the physical structures of the infalling envelope around a pro…

Insights on the Sun birth environment in the context of star-cluster formation in hub-filament systems
Doris Arzoumanian, Sota Arakawa, Masato I. N. Kobayashi +7
Cylindrical molecular filaments are observed to be the main sites of Sun-like star formation, while massive stars form in dense hubs, at the junction of multiple filaments. The rol…
Effective dust growth in laminar circumplanetary discs with magnetic wind-driven accretion
Yuhito Shibaike, Shoji Mori
It has been considered that large satellites around gas planets form in-situ circumplanetary discs (CPDs). However, dust particles supplied into CPDs drift toward the central plane…
