Dynamical Impacts of Accretion Streamers on Protoplanetary Disks
Han-Gyeol Yun, Jeong-Eun Lee, Jaehan Bae +1
Recent observations suggest that accretion streamers are common in protoplanetary disks, yet their dynamical impact on disk evolution remains poorly understood. Using three-dimensi…
JWST/MIRI Imaging Search for Kinematically Detected Protoplanetary Candidates
G. Cugno, M. Benisty, R. Teague +32
Kinematic perturbations observed with ALMA in CO line emission provide evidence for a population of embedded giant protoplanets shaping the structure of protoplanetary disks. We pr…
Dust Substructures and Line Perturbations driven by a Forming Planet in J16120
Anibal Sierra, Andrés F. Izquierdo, Paola Pinilla +18
Hints of planet formation have been independently reported within the gap of the disc around 2MASS J16120668-301027 from millimetre continuum, infrared, and H-alpha observations. I…
Mapping the WISPIT2 Planet-Hosting Cavity at Sub-Hill-Radius scales
Myriam Benisty, Stefano Facchini, Richard Teague +6
We present new deep, very high angular resolution observations of the sub-mm continuum (19x13 mas) and 12CO (67x52 mas) emission from the disk surrounding the planet host WISPIT2.…
A Streamer Driving Misalignment in the Circumtriple Disk of GW Ori
Maria Galloway-Sprietsma, Jaehan Bae, Toni Phillips +5
GW Orionis is a triple stellar system with a disk featuring three misaligned dust rings. We present ALMA molecular line data of CO isotopologues, revealing a streamer feeding the d…
Extending dynamical mass measurements: probing GI as a possible origin of mm-dust spirals
V. Pezzotta, S. Facchini, A. F. Izquierdo +7
Constraining the total mass of protoplanetary disks is crucial to determine the availability of material for planet formation. Yet, providing accurate and precise measurements of t…
The Circumbinary Disc of HD 34700A II. Analysis of a strong dust asymmetry
Daniele Fasano, Myriam Benisty, Jochen Stadler +8
ALMA observations have shown that substructures are ubiquitous in protoplanetary discs. A sub-group, the transition discs, shows large cavities and rings in dust continuum. Among t…
exoALMA XX: Tomographic Detection of Embedded Planets in Protoplanetary Disks
Andres F. Izquierdo, Jaehan Bae, Stefano Facchini +32
The exoALMA Large Program has revealed a wealth of substructures in the dust and molecular line emission of several protoplanetary discs, suggesting that planet formation may unfol…
exoALMA XXIII. Estimating Disk and Planet Properties from Dust Morphologies with DBNets2.0
Alessandro Ruzza, Giuseppe Lodato, Giovanni Rosotti +21
The exoALMA large program provided an unprecedented view of the morphology and kinematics of 15 circumstellar disks, offering a biased but homogenous and well-characterized sample…
exoALMA. XXIV. Formaldehyde Emission in Protoplanetary Disks of exoALMA Compared with Their Properties and Dynamical State
Felipe Alarcón, Stefano Facchini, Leon Trapman +15
The presence of asymmetries and substructures in protoplanetary disks, revealed by both dust and gas emission, highlights the potential interplay and the broader connection between…
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…
Circumplanetary Disk Candidate in the Disk of HD 163296 Traced by Localized Emission from Simple Organics
Andres F. Izquierdo, Jaehan Bae, Maria Galloway-Sprietsma +6
Atacama Large Millimeter/submillimeter Array observations suggest that the disc of HD 163296 is being actively shaped by embedded, yet unseen protoplanets, as indicated by numerous…
On The Orbital Evolution of Multiple Wide Super-Jupiters: How Disk Migration and Dispersal Shape the Stability of The PDS 70 System
Clarissa R. Do Ó, Jaehan Bae, Quinn M. Konopacky +4
Direct imaging has revealed exoplanet systems hosting multiple wide-orbit Super-Jupiters, where planet-planet interactions can shape their long-term dynamical evolution. These stro…
Enhanced Pebble Drift Across Planet-Opened Gaps in Windy Protoplanetary Disks
Lorraine Nicholson, Jaehan Bae
When a giant planet forms in a protoplanetary disks, it carves a gap around its orbit separating the disk into two parts: inner disk and outer disk. Traditional disk accretion mode…
Direct Measurement of Extinction in a Planet-Hosting Gap
G. Cugno, S. Facchini, F. Alarcon +12
Recent disk observations have revealed multiple indirect signatures of forming gas giant planets, but high-contrast imaging has rarely confirmed the presence of the suspected pertu…
