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…

exoALMA XI: ALMA Observations and Hydrodynamic Models of LkCa 15: Implications for Planetary Mass Companions in the Dust Continuum Cavity
Charles H. Gardner, Andrea Isella, Hui Li +43
In the past decade, the Atacama Large Millimeter/submillimeter Array (ALMA) has revealed a plethora of substructures in the disks surrounding young stars. These substructures have…

Constraints on the physical origin of large cavities in transition disks from multi-wavelength dust continuum emission
Anibal Sierra, Laura M. Pérez, BenjamÃn Sotomayor +8
The physical origin of the large cavities observed in transition disks is to date still unclear. Different physical mechanisms (e.g., a companion, dead zones, enhanced grain growth…
