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,…
Interpreting the scattering surface in protoplanetary disks
Massimiliano Bolchini, Giovanni Rosotti, Marion Villenave +5
In recent years, extreme adaptive optics have enabled high-resolution, high-contrast scattered-light observations of protoplanetary disks. Interpreting these observations requires…
Dust characterization of halos: The extended emission in protoplanetary disks
Sreejita Das, Enrique MacÃas, Nicolas T. Kurtovic +3
Extended low surface brightness emission has been identified in a number of protoplanetary disks, in tension with predictions of radial drift theory. We aim to investigate the natu…
Grain growth in protoplanetary disks in the Upper Scorpius revealed by millimeter-wave spectral indices
Tau Bito, Akimasa Kataoka, Takahiro Ueda +3
The measurement of dust size from millimeter-wavelength spectra provides direct constraints on grain growth in protoplanetary disks. The spectral indices between 0.88 mm and 2.9 mm…
Detailed Microwave Continuum Spectra from Bright Protoplanetary Disks in Taurus
Caleb Painter, Sean M. Andrews, Claire J. Chandler +9
We present new observations that densely sample the microwave (4-360 GHz) continuum spectra from eight young systems in the Taurus region. Multi-component, empirical model prescrip…
Spirals, rings, and vortices shaped by shadows in protoplanetary disks: from radiative hydrodynamical simulations to observable signatures
Alexandros Ziampras, Cornelis P. Dullemond, Tilman Birnstiel +2
Numerous protoplanetary disks exhibit shadows in scattered light observations. These shadows are typically cast by misaligned inner disks and are associated with observable structu…
