Demographics of planet-forming disks with the SKAO
Antonio Garufi, Sebastián Pérez, John D. Ilee +21
Understanding how solid material in planet-forming disks evolves from micron-sized dust to planetary cores is a central challenge in modern astrophysics. This study has advanced dr…
Substructures in Planet-Forming Disks with the SKAO
Yinhao Wu, Jessica Speedie, Sebastián Pérez +33
Disks of gas and dust orbiting young stars are the arenas and material reservoirs for planet formation. Over the past decade, multiwavelength observations, from infrared to radio,…
Reading between the rings: observed dust ring properties as probes of planet masses
Amena Faruqi, Jessica Speedie, Ralph E. Pudritz +1
We hypothesise that dust rings in protoplanetary discs formed by an embedded planet should have properties that reflect the planet's mass. We use 2D hydrodynamical simulations of p…
Dynamical Mass Constraints on Transition Disk Perturbers with the G23H Catalog
Dori Blakely, William Thompson, Doug Johnstone +14
We present dynamical mass constraints on perturbers in 11 transition disk systems using a novel combination of calibrated Hipparcos and Gaia absolute astrometry data. Out of the sa…
Detecting and Characterizing Companions with a Calibrated Gaia DR2, DR3, and Hipparcos Catalog (G23H)
William Thompson, Dori Blakely, Jerry W. Xuan +16
Gaia DR4 epoch astrometry will enable the detection of thousands of exoplanets through astrometric motion. Here, we present a composite catalog and modeling framework that extracts…
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…
