The star-forming core ahead of HH 80N: studying the interaction with a parsec scale jet.

HH 80N is the north counterpart of the HH 80/8l/80N system, the largest collimated stellar jet known up te date, located at 1.7 kpc in Sagittarius. Ahead of HH 80N, there is a dense eore (HH SON eore) that exhibits peculiar chemistry and kinematics, and has  star formation signatures. In this thesis we focus our study on the possible

influence of the HH 80/8l/80N jet on the HH 80N coreo First, we find that the UV radiation of HH SON can alter the chemistry in the part of the eore more ex po sed to the HH object. Second, despite a possible dynamical ¡nfluence of the jet ta the HH SON care, the callapse  pracess of the HH SON core can be explained in the 'c1assic' frame of

star formation. Finally, we discuss the role of the outflow inducing the star formation observed in this coreo.
