The main objective of this work is to study the gas distribution, traced by the emission lines produced by the abundance of molecules presents in the gas, detected in millimeter waves, in the protoplanetary disk of the young star HD 163296, which have a big disk and clear rings around it. We research for the distribution of the gas emission, using ALMA data measured in the cycle 6, through several different sources. More specifically we are looking for resolve the gas structure based on 12CO, 13CO and C18O molecular line emission, to determine their distribution on the disk and how they participate in the planets formation process. As a summary of what the reader can found in the body of this work, it start with the introduction - in 1 - about what are the protoplanetary disks, the interest in the chemistry to study how the planet can be form. To continue in 2, with the description of the observation and data reduction techniques used to clean data and get the images. Then, we present method implemented to estimate the gas density in the 3, and the results in 4.
Discussion and analysis of results in 5, and finally a summary with main results extracted of our work in 6.
