SO emission in the dynamically perturbed protoplanetary disks around CQ Tau and MWC 758
Francesco Zagaria, Haochang Jiang, Gianni Cataldi +25
We report the serendipitous detection of the SO (219.949 GHz) rotational transition in archival Atacama Large Millimeter/submillimeter Array (ALMA) observations of th…
Differentiating Formation Models with New Dynamical Masses for the PDS 70 Protoplanets
David Trevascus, Sarah Blunt, Valentin Christiaens +22
Hot- and cold-start planet formation models predict differing luminosities for the young, bright planets that direct imaging surveys are most sensitive to. However, precise mass es…
exoALMA VII: Benchmarking Hydrodynamics and Radiative Transfer Codes
Jaehan Bae, Mario Flock, Andres Izquierdo +25
Forward modeling is often used to interpret substructures observed in protoplanetary disks. To ensure the robustness and consistency of the current forward modeling approach from t…
Keplerian motion of a compact source orbiting the inner disc of PDS 70: a third protoplanet in resonance with b and c?
Iain Hammond, Valentin Christiaens, Daniel J. Price +10
The disc around PDS 70 hosts two directly imaged protoplanets in a gap. Previous VLT/SPHERE and recent James Webb Space Telescope/NIRCam observations have hinted at the presence of…
exoALMA. VI. Rotating under Pressure: Rotation curves, azimuthal velocity substructures, and pressure variations
Jochen Stadler, Myriam Benisty, Andrew J. Winter +36
The bulk motion of the gas in protoplanetary disks around newborn stars is nearly Keplerian. By leveraging the high angular and spectral resolution of ALMA, we can detect small-sca…
exoALMA III: Line-intensity Modeling and System Property Extraction from Protoplanetary Disks
Andrés F. Izquierdo, Jochen Stadler, Maria Galloway-Sprietsma +37
The ALMA large program exoALMA offers a unique window into the three-dimensional physical and dynamical properties of 15 circumstellar disks where planets may be actively forming.…
exoALMA. VIII. Probabilistic Moment Maps and Data Products using Non-parametric Linear Models
Thomas Hilder, Andrew R. Casey, Daniel J. Price +33
Extracting robust inferences on physical quantities from disk kinematics measured from Doppler-shifted molecular line emission is challenging due to the data's size and complexity.…
exoALMA XII: Weighing and sizing exoALMA disks with rotation curve modelling
Cristiano Longarini, Giuseppe Lodato, Giovanni Rosotti +38
The exoALMA large program offers a unique opportunity to investigate the fundamental properties of protoplanetary disks, such as their masses and sizes, providing important insight…
exoALMA. X. channel maps reveal complex CO abundance distributions and a variety of kinematic structures with evidence for embedded planets
Christophe Pinte, John D. Ilee, Jane Huang +34
We analyze the CO data cubes of the disks in the exoALMA program. 13/15 disks reveal a variety of kinematic substructures in individual channels: large-scale arcs or…
exoALMA I. Science Goals, Project Design and Data Products
Richard Teague, Myriam Benisty, Stefano Facchini +40
Planet formation is a hugely dynamic process requiring the transport, concentration and assimilation of gas and dust to form the first planetesimals and cores. With access to extre…
