Dust characterization of the HD 163296 disk with high-resolution multi-wavelength ALMA observations
Kiyoaki Doi, Myriam Benisty, Akimasa Kataoka +10
Context. Planets form through the growth and accumulation of dust grains in protoplanetary disks. Characterizing dust properties such as size, surface density, and temperature is k…
Interpreting ALMA Multiwavelength Continuum Observations of PDS 70 c: An Optically Thick Dust Ring in the Circumplanetary Disk
Yuhito Shibaike, Satoshi Okuzumi, Takahiro Ueda +2
Giant planets form small gas disks, called circumplanetary disks (CPDs), during gas accretion. The CPD of PDS 70 c has been detected by the Atacama Large Millimeter/submillimeter A…
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,…
Thermal instability and rocky planetesimal formation in the inner regions of protoplanetary disks
Ryo Kato, Takahiro Ueda, Satoshi Okuzumi
The inner regions of protoplanetary disks are promising formation sites of rocky planetesimals. Theoretical studies have proposed that dust trapping at the magnetorotational instab…
Multi-wavelength ALMA Imaging of HD 34282: Dust-trapping Signatures of a Vortex Candidate
Xiaoyi Ma, Fangyuan Yu, Ruobing Dong +8
Azimuthal arcs in millimeter continuum emission from protoplanetary disks are often attributed to dust-trapping vortices, but definitive observational confirmation of vortices rema…
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…
