Dust characterization of the HD 163296 disk with high-resolution multi-wavelength ALMA observations
Kiyoaki Doi, Myriam Benisty, Akimasa Kataoka +10
Context. Planets form through the growth and accumulation of dust grains in protoplanetary disks. Characterizing dust properties such as size, surface density, and temperature is k…
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…
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…
exoALMA XXI: The Morphology and Dynamics of Vertical Flows
Myriam Benisty, Andres F. Izquierdo, Jochen Stadler +33
Vertical gas flows, such as winds and meridional circulations, are natural outcomes of protoplanetary disk processes and play a critical role in the earliest stages of planet forma…
exoALMA XIX: Confirmation of Non-thermal Line Broadening in the DM Tau Protoplanetary Disk
Caitlyn Hardiman, Christophe Pinte, Daniel J. Price +38
Turbulence is expected to transport angular momentum and drive mass accretion in protoplanetary disks. One way to directly measure turbulent motion in disks is through molecular li…
On the Interpretation of Velocity Residuals in Protoplanetary Disks
Masataka Aizawa, Ryuta Orihara
We present a first-order analytical model for line-of-sight velocity residuals, defined as the difference between observed velocities and those predicted by a fiducial model, assum…
