 Dusty perspectives on the cradles of planets
In this talk, I will present a brief overview of my PhD work, in which I used high-resolution radio observations from ALMA and VLA to investigate planet formation and disk substructures. The main goal was to understand how and when disk substructures form and how they relate to dust growth and planets. To address this, we studied two young systems, such as IRAS4A and HL Tau, as well as a population of disks in the nearby Lupus star-forming region. We asked whether substructures can be detected in optically thick environments and at optically thick wavelengths; whether the chemical structure of embedded young disks shows signatures of dust evolution, and, finally, whether substructures are only truly confined to large, massive disks or simply unresolved and hidden in compact disks. Together, the results of my PhD suggest that planet formation may begin very early in the disk lifetime, with important implications for how common planetary systems like our own may be. We also concluded that there is substantial value in studying small disks and optically thick regions with ALMA, beyond the brightest and largest disks, as these places provide equally important insights into disk structure and evolution.
