Its coupling with the dust is the key to our understanding of planetary formation. Studying the gas content is therefore a crucial step towards understanding protoplanetary discs evolution. Such a study can be made through spectroscopic observations of emission lines in the FIR, where some of the most important gas coolants emit, such as the [OI] 3P1 → 3P2 transition at 63.18 μm. <BR /> Aims: We aim at characterising the gas content of protoplanetary discs in the intermediate-aged (from the perspective of the disc lifetime) Chamaeleon | Free Keywords: | circumstellar matter; stars: evolution; astrochemistry; protoplanetary disks | External Publication Status: | published | Document Type: | Article |
