Abstract: | Observations of pre-main sequence objects (T Tauri, Herbig Ae/Be and FU Orionis stars) obtained with the instrumentation on
board the Infrared Space Observatory (ISO) are reviewed. All the observations have been mainly carried out by using the two
spectrographs SWS and LWS, adopting their low resolution modes and such data have been used both for lines detection and to
reconstruct the spectral energy distributions. Line emission and photometric behaviour of pre-main sequence objects have been
analyzed in the framework of the current models, discussing the agreement (or disagreement) with them and trying to derive
the questions which should be answered by the forthcoming FIR instrumentation.
Based on observations with ISO, an ESA project with instruments funded by ESA Member States (especially the PI countries:
France, Germany, The Netherlands, and the United Kingdom), and with the participation of ISAS and NASA. |
