We report on near-infrared J- and H-band linear polarimetric photometry of eight ultracool dwarfs (two late-M, five L0-L7.5, and one T2.5) with known evidence for photometric variability due to dust clouds, anomalous red infrared colors, or low-gravity atmospheres. The polarimetric data were acquired with the LIRIS instrument on the William

We present near-infrared spectra of 23 B-type asteroids obtained with the NICS cameraspectrograph at the 3.56 m Telescopio Nazionale Galileo. We also include visible and near-infrared spectra of 20 additional B-type asteroids from the literature, including near-Earth asteroid 1999 RQ36, primary target of NASA's OSIRIS-Rex sample return mission. A

Results from a photometric search for extrasolar planetary transits across the eclipsing binary CM Dra are presented. The TEP (Transits of Extrasolar Planets) network has observed this star since 1994, and a lightcurve with 617 hours of coverage has been obtained. The data give a complete phase coverage of the CM Dra system at each of the 3 years

We present the first part of the first large and homogeneous CCD color-magnitude diagram (CMD) data base, comprising 52 nearby Galactic globular clusters (GGC) imaged in the V and I bands using only two telescopes (one for each hemisphere). The observed clusters represent 75% of the known Galactic globulars with (m-M)V

We propose to carry out full-synthesis (12-h) HI ATCA observations of 8 bright Blue Compact Dwarf Galaxies (BCDGs), for which we have already got interesting results. Some are apparently isolated, others belong to galaxy groups. We want to estimate the distribution of the HI in each BCDG and its surrounding, looking for independent HI clouds or

We analyse the chemical composition of the planetary nebula (PN) NGC 5315, through high-resolution (R ∼ 40000) optical spectroscopy with Ultraviolet-Visual Echelle Spectrograph at the Very Large Telescope, and medium-resolution (R ∼ 4800) near-infrared spectroscopy with Folded-port InfraRed Echellette at Magellan Baade Telescope, covering a wide
