The Circumbinary Disk of HD 34700A: I. CO gas kinematics indicate spirals, infall, and vortex motions
J. Stadler, M. Benisty, F. Zagaria +9
We present the first high-resolution ( 0.14") Atacama Large Millimeter/submillimeter Array (ALMA) Band 6 dust continuum and CO molecular line emission observations of the qua…
ExoALMA XIII. gas masses from N2H+ and C18O: a comparison of protoplanetary gas disk mass measurement techniques
Leon Trapman, Cristiano Longarini, Giovanni P. Rosotti +37
The gas masses of protoplanetary disks are important but elusive quantities. In this work we present new ALMA observations of N2H+ (3-2) for 11 exoALMA disks. N2H+ is a molecule se…
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…
exoALMA II: Data Calibration and Imaging Pipeline
Ryan A. Loomis, Stefano Facchini, Myriam Benisty +30
The exoALMA Large Program was designed to search for subtle kinematic deviations from Keplerian motion, indicative of embedded planets, in high angular and spectral resolution Band…
exoALMA XI: ALMA Observations and Hydrodynamic Models of LkCa 15: Implications for Planetary Mass Companions in the Dust Continuum Cavity
Charles H. Gardner, Andrea Isella, Hui Li +43
In the past decade, the Atacama Large Millimeter/submillimeter Array (ALMA) has revealed a plethora of substructures in the disks surrounding young stars. These substructures have…
exoALMA IX: Regularized Maximum Likelihood Imaging of Non-Keplerian Features
Brianna Zawadzki, Ian Czekala, Maria Galloway-Sprietsma +32
The planet-hunting ALMA large program exoALMA observed 15 protoplanetary disks at ~0.15" angular resolution and ~100 m/s spectral resolution, characterizing disk structures and kin…
