We present the observations of the Cataclysmic Variable AE Aquarii by 3 instruments of ISO in the previously unexplored range of 4.8-170 microns during a multi-wavelength campaign from the radio to visible wavelengths. Up to 7.3 microns, the major contribution comes from the secondary, with probably some additional cyclotron radiation from the

The kinematics and physical conditions of the bipolar planetary nebula M 2-48 are analysed from high and low dispersion long-slit spectra. Previous CCD narrow-band optical observations have suggested that this nebula is mainly formed by a pair of symmetric bow-shocks, an off-center semi-circular shell, and an internal bipolar structure. The bipolar

We report complete near-infrared (0.9-2.4 mu m) spectral observations of the largest know trans-Neptunian objects (TNO) 28976 = 2001 KX76 taken in two different nights using the new Near Infrared Camera Spectrometer (NICS) attached to the 3.56 m Telescopio Nazionale Galileo (TNG). The spectra are featureless and correspond to a neutral colored

We present near-IR spectroscopy of a sample of 30 IRAS sources recently identified as late AGB stars, post-AGB stars or early PNe. The spectra obtained are centered at various wavelengths covering the molecular hydrogen v=1-> 0 S(1) 2.122 mu m and v=2->1 S(1) 2.248 mu m emission lines, the recombination lines of hydrogen Brgamma 2.166 mu m, Pfgamma

We present a theoretical model for the observed mass functions (MF's) of interstellar clouds, and test it by comparison with interferometrically observed MF's. We consider the time evolution of velocities using the stochastic differential Langevin equation for the objects (in fact gas clumps of sizes below 1pc) under Brownian motion, with friction

We present deep L- (3.8 μm) and M- (4.7 μm) band imaging with the Infrared Spectrometer and Array Camera (ISAAC) on the ESO Very Large Telescope (VLT) with unprecedented spatial resolution of the nearby Seyfert 2 galaxies NGC 7496 and NGC 7582 and the Seyfert 1 galaxy NGC 7213, all at a comparable distance.
