exoALMA XXII: A Two-dimensional Atlas of Deviations from Keplerian Disks
Misato Fukagawa, Andrés F. Izquierdo, Jochen Stadler +35
Protoplanetary disks are the birthplaces of planetary systems, and deviations from Keplerian rotation imprinted in disk gas kinematics serve as key tracers of physical processes an…
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…
Shadow-Based Framework for Estimating Transition Disk Geometries
Ryuta Orihara, Munetake Momose
Some transition disks host misaligned inner disks with radii of several au. Understanding the geometric and physical properties of these misaligned disks is essential for advancing…
Discovery of Jet-Bubble-Disk Interaction: Jet Feedback on a Protoplanetary Disk via an Expanding Bubble in WSB 52
Masataka Aizawa, Ryuta Orihara, Munetake Momose
While stellar jets and outflows are fueled by accretion from disks, their direct influence on disks remain unexplored. Here we revisit ALMA observations of $^{12}\mathrm{CO}\,(J=2-…
exoALMA XIV. Gas Surface Densities in the RX J1604.3-2130 A Disk from Pressure-broadened CO Line Wings
Tomohiro C. Yoshida, Pietro Curone, Jochen Stadler +31
The gas surface density is one of the most relevant physical quantities in protoplanetary disks. However, its precise measurement remains highly challenging due to the lack of a di…
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…
