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…
Search for Exoplanetary Ring Systems with TESS
Tsubasa Umetani, Masataka Aizawa, Yuichiro Ezoe +1
Photometric surveys for exoplanetary ring systems have not confirmed any object with Saturn-sized ring. We systematically analyse 308 TESS planet candidates, mainly comprised of gi…
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-…
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…
