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

Solar global oscillations have now been measured for more than 20 years. The study of these modes has contributed to improve, along time, the description of the solar core. We have now a proper access to this part of the Sun, with ground networks observing for more than 10 years and the three instruments aboard SOHO in a quasi continuous mode for

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

A negative sign was omitted from the absolute magnitude estimate of M32's bulge. In the last sentence of the fifth paragraph of § 2.1, it should read -16.34.

We are developing a project aimed at studying the physical properties, origin and evolution of low-ionization structures in planetary nebulae. Within this project we have identified a number of pairs of highly collimated low-ionization jet-like features (Gonçalves et al. 2001). In spite of being very similar to real jets, they have the intriguing

We report on our continuing effort to identify extremely low-mass members of the cluster around the hot star sigma Orionis. Using the KeckI telescope in Hawaii and the Isaac Newton telescope in La Palma, we carried out a deep near-infrared and optical search in an area of 55 square arcminutes, which has yielded the discovery of an object with blue
