Description
Planets form within protoplanetary disks; therefore, understanding the diversity of planetary compositions requires studying how material is distributed and evolves within these disks. During their first million years, young disks remain embedded in the envelopes of natal molecular clouds and continue to accrete material. This accreting material alters the disk’s physical and thermal structure and undergoes chemical processing as environmental conditions change. With recent evidence suggesting that planet formation may begin during this embedded stage, it becomes essential to characterize the physical and chemical evolution of such systems. Current and upcoming facilities like JWST (James Webb Space Telescope), ELT/METIS (Extremely Large Telescope/Mid-infrared ELT Imager and Spectrograph), and PRIMA (PRobe far-Infrared Mission for Astrophysics) offer unprecedented spectral and spatial resolution at infrared wavelengths, providing new opportunities to probe planet-forming regions in embedded disks. To complement these observations, we develop a grid of 2D thermo-chemical models incorporating both disk and envelope components using the DALI (Dust And LIne) code. We focus on the dominant physical and chemical processes governing the distribution and evolution of material in embedded disks. We will present the initial results from the study and discuss the evolution of the physical-chemical structure of the disk during its embedded phase.
