Probing disk dynamics and dust evolution through shadows in protoplanetary disks: A case study of the HD 142527 disk

Yuya Fukuhara, Ryuta Orihara, Satoshi Okuzumi +1

Planet formation begins with dust growth and planetesimal formation within protoplanetary disks surrounding young stars. To understand these processes, it is essential to estimate…

Axisymmetric Modeling of DSHARP Dusty Disks: Asymmetric Structures and Inner-Disk Dispersal

Masataka Aizawa, Takayuki Muto, Munetake Momose

High-resolution observations of Class II protoplanetary disks frequently reveal annular structures that may indicate the presence of embedded planets. In this study, we model brigh…

Observationally derived magnetic field strength and 3D components in the HD 142527 disk

Satoshi Ohashi, Takayuki Muto, Yusuke Tsukamoto +5

In protoplanetary disks around young stars, magnetic fields play an important role for disk evolution and planet formation. Polarized thermal emission from magnetically aligned gra…

Revealing asymmetry on midplane of proto-planetary disc through modelling of axisymmetric emission: methodology

Masataka Aizawa, Takayuki Muto, Munetake Momose

This study proposes an analytical framework for deriving the surface brightness profile and geometry of a geometrically-thin axisymmetric disc from interferometric observation of c…

Modeling protoplanetary disk heating by planet-induced spiral shocks

Tomohiro Ono, Tatsuki Okamura, Satoshi Okuzumi +1

We investigate the heating of protoplanetary disks caused by shocks associated with spiral density waves induced by an embedded planet. Using two-dimensional hydrodynamical simulat…
