- 요약Planets are born within young circumstellar disks that formed from the collapse of a centrally concentrated dense core within molecular clouds. It is during this gas-rich protoplanetary disk stage that gas giant planets capture the volatile-rich gaseous material that will be part of their atmospheres. Moreover, the physical state of protoplanetary disks is constantly evolving and these changes affect the chemistry of the disk and how planets form. Different chemical and physical processes take place in a protoplanetary disk during its evolution and the gap carved in it by a giant planet. These processes include grain evolution, photochemistry, sublimation and condensation of molecular species and active gas-phase chemistry. Current surveys of protoplanetary disks at high spatial resolution have shown that substructures in the dust continuum emission are frequent. The presence of substructures is usually linked to the presence of incipient and ongoing planet formation. Under this light, a range of studies have shown that the chemical compositions and abundance ratios around dynamical planet-forming regions are key for the evolution and components of planetary atmospheres. Furthermore, high spatial resolution observations of molecular line and dust continuum emission of protoplanetary disks provide us with an unprecedented benchmark to understand the physical and chemical evolution of the disk, enabling the testing of different model setups including the influence of protoplanets in their host disk. This thesis intends to push the knowledge about the chemical composition of the gas being fed into protoplanets through a theoretical approach. This knowledge is key in predicting the compositions of planetary atmospheres and their origins.Additionally, we aim to provide constraints to the community to understand the results of protoplanet-hunting campaigns in the infrared and millimeter, while optimizing the design of surveys with upcoming instruments. Enhancing the detection rate of protoplanets will significantly improve our knowledge of their growth and their dynamic interplay with the surrounding circumstellar disks.
