Seminario DAS: Dust Continuum Analysis of The ALMA Disk-Exoplanet C/Onnection (DECO) sample

Abstract: Protoplanetary disks set the initial composition of future planetary systems. Comparing the chemistry of disks to the compositions of exoplanet atmospheres informs our understanding of the planet-formation process. This is the main focus of the ALMA Disk-Exoplanet C/Onnection (DECO) large program. It observed 80 disks across four star-forming regions sampling a range of stellar masses, disk sizes, and environments. During this talk, I will focus on the dust continuum emission of the DECO sample. We fit the continuum visibilities of the dust emission to extract the highest angular resolution from the data and thus constrain the system geometry, dust morphology, disk radii, and presence of substructures. Comparing these results with the disk chemistry found in this survey will revolutionize our understanding of the chemical diversity occurring in more "typical" disks and how it imprints on the diversity of exoplanet populations.
