ISO Observations of Pre-Stellar Cores and Young Stellar Objectsples of sources in different evolutionary stages are reviewed, addressing in particular how the physical and chemical properties of the proto-stellar environments change from the pre-stellar cores to the protostars at the end of their accretion phase. In addition, the mid-IR surveys in nearby star-f

Pre-Main Sequence Stars Seen by ISObservatory (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 b

Late Stages of Stellar Evolutiontalline silicates and the rotational lines of water vapour, were detected for the first time in the spectra of (post-)Asymptotic Giant Branch (AGB) stars. Their analysis has greatly improved our knowledge of stellar atmospheres and circumstellar environments. A surprising number of objects, particul

The Cool Interstellar Mediumrstanding of the physics and chemistry of the gas, the nature and evolution of the dust grains and also the coupling between the gas and the grains. We review here the ISO results on the cool and low-excitation regions of the interstellar medium, where . .? 500 K, .H ～ 100–10. cm. and the electron d
