Hints of planet formation signatures in a large-cavity disk studied in the AGE-PRO ALMA Large Program
Anibal Sierra, Laura M. Pérez, Carolina Agurto-Gangas +19
Detecting planet signatures in protoplanetary disks is fundamental to understanding how and where planets form. In this work, we report dust and gas observational hints of planet f…

High angular resolution evidence of dust traps from deep ALMA Band 3 observations of LkCa15
Anibal Sierra, Paola Pinilla, Laura Pérez +5
Dust traps are the most promising mechanisms to explain the observed substructures in protoplanetary discs. In this work, we present high-angular resolution (60 mas, 9.4 au)…

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…
