A Protoplanet Candidate in the PDS 66 Disk Indicated by Silicon Sulfide Isotopologues
Tomohiro C. Yoshida, Felipe Alarcón, Jaehan Bae +11
Despite observational progress in planet formation, the stage in which planetesimals grow into planets remains poorly understood. During this phase, protoplanets may develop gaseou…
A 2 au resolution view by ALMA of the planet-hosting WISPIT 2 disk
Stefano Facchini, Pietro Curone, Myriam Benisty +4
We present deep, high spatial resolution interferometric observations of 0.88 mm continuum emission from the TYC 5709-354-1 system, hereafter WISPIT 2, obtained with the goal of de…
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…
Tracing Pebble Drift History in Two Protoplanetary Disks with CO Enhancement
Tayt Armitage, Joe Williams, Ke Zhang +15
Pebble drift is an important mechanism for supplying the materials needed to build planets in the inner region of protoplanetary disks. Thus, constraining pebble drift's timescales…
A Submillimeter Survey of CS Excitation in Protoplanetary Disks: Evidence of X-ray-Driven Sulfur Chemistry
Charles J. Law, Romane Le Gal, Karin I. Ãberg +12
The sulfur chemistry in protoplanetary disks influences the properties of nascent planets, including potential habitability. Although the inventory of sulfur molecules in disks has…
exoALMA. XVIII. Interpreting large scale kinematic structures as moderate warping
Andrew J. Winter, Myriam Benisty, Andrés F. Izquierdo +28
The exoALMA program gave an unprecedented view of the complex kinematics of protoplanetary disks, revealing diverse structures that remain poorly understood. We show that moderate…
