Late Stages of Stellar Evolution
Blommaert, Joris A. D. L.; Cami, Jan; Szczerba, Ryszard +1 more
A large fraction of ISO observing time was used to study the late stages of stellar evolution. Many molecular and solid state features, including crystalline 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 know…
Energetic Particles in the Magnetosphere of Saturn and a Comparison with Jupiter

Understanding Galaxy Formation with ISO Deep Surveys
Elbaz, David
We present the results obtained through the various ISO extragalactic deep surveys. Although IRAS revealed the existence of galaxies forming stars at a rate of a few tens (LIRGs) or even hundreds (ULIRGs) solar masses in the local universe, ISO not only discovered that these galaxies were already in place at redshift one, but also that they are no…
Pre-Main Sequence Stars Seen by ISO
Lorenzetti, Dario
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 …
Comets, Asteroids and Zodiacal Light as Seen by Iso
Ábrahám, Péter; Müller, Thomas G.; Crovisier, Jacques
ISO performed a large variety of observing programmes on comets, asteroids and zodiacal light covering about 1% of the archived observations with a surprisingly rewarding scientific return. Outstanding results were related to the exceptionally bright comet Hale Bopp and to ISO's capability to study in detail the water spectrum in a direct way. But…
The Cool Interstellar Medium
Miville-Deschênes, Marc-Antoine; Verstraete, Laurent; Abergel, Alain +2 more
Infrared spectroscopy and photometry with ISO covering most of the emission range of the interstellar medium has led to important progress in the understanding 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…
High Excitation ISM and Gas
Peeters, Els; Rodríguez-Fernández, Nemesio J.; Martín-Hernández, Nieves Leticia +1 more
An overview is given of ISO results on regions of high excitation ISM and gas, i.e. H II regions, the Galactic Centre and Supernova Remnants. IR emission due to fine-structure lines, molecular hydrogen, silicates, polycyclic aromatic hydrocarbons and dust are summarised, their diagnostic capabilities illustrated and their implications highlighted.
The Earth's Magnetopause: Reconstruction of Motion and Structure
de Keyser, Johan
The Earth’s magnetosphere is an accessible region for improving our knowledge of the dynamics of collisionless plasmas. We focus here on the magnetopause a typical plasma discontinuity. We discuss recent developments in describing the structure of the magnetopause by means of reconstruction techniques, which translate in situ data into spatial inf…
The European Large Area ISO Survey
Oliver, Seb; Pozzi, Francesca
The European Large Area ISO Survey (ELAIS) was the largest Open Time survey on the Infrared Space Observatory (ISO). It was designed to explore obscured galaxies and hence quantify the recent star-formation history of the Universe. The final reanalysis of the data has been completed and a band-merged catalogue with associations across many wavelen…
Debris Discs Around Stars: The 2004 ISO Legacy
de Muizon, Marie Jourdain
Debris discs around stars were first discovered by the Infrared Astronomical Satellite (IRAS) in 1983. For the first time material orbiting another star than the Sun, but distinct from a circumstellar envelope, was observed through its far infrared emission. This major discovery motivated astronomers to investigate those discs by further analyzing…
