An SMA Molecular Inventory of the Edge-on Protoplanetary Disk Gomez's Hamburger
Erin M. Cusson, Lisa Wölfer, Richard Teague +10
Gomez's Hamburger (IRAS 18059-3211, GoHam) is a massive, edge-on protoplanetary disk that is potentially gravitationally unstable and hosts an overdensity that may be the site of a…
The 12CO Gas Structures of Protoplanetary Disks in the Upper Scorpius Region
Luigi Zallio, Giovanni P. Rosotti, Miguel Vioque +13
We present measurements of key protoplanetary disk properties inferred from parametric models of ALMA 12CO spectral line visibilities. We derive gas-disk radii, integrated fluxes,…
Compact CO emission and no evidence of radial drift. ALMA observations of the faintest planet-forming disks in Lupus
Giulia Ricciardi, Francesco Zagaria, Anna Miotello +13
A large fraction of planet-forming disks observed with ALMA show faint CO emission, often interpreted as strong CO depletion. However, faint emission may also arise from spatially…
Large Dust Grains and a Possible Dust Trap in the Polar Circumbinary Disc of HD 98800B
Ãlvaro Ribas, Thomas Lack, Francesco Zagaria +6
HD 98800 is a nearby hierarchical quadruple system comprising two binaries orbiting each other. Surprisingly, despite its 10 Myr age and dynamic environment, the Ba-Bb compo…
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…
