P.; Barrado, D.; Eiroa, C.; Duchêne, G.; Montesinos, B.; Mathews, G.; Podio, L.; Dent, W. R. F.; Huélamo, N.; Merín, B. Date of Publication (YYYY-MM-DD): 2015 Title of Journal: Astronomy and Astrophysics Volume: 575 Start Page: id. A19 (10 pp) Audience: Not Specified Abstract / Description: Context. Gas plays a major role in the dynamical evolution of protoplanetary discs. 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 Communicated by: N.
