  • Brown dwarfs in the Pleiades cluster. II. J, H and K photometry.
    We have obtained near-infrared observations of some of the faintest objects so far known towards the Pleiades young stellar cluster, with the purpose of investigating the sequence that connects cluster very low-mass stars with substellar objects. We find that infrared data combined with optical magnitudes are a useful tool to discriminate cluster

  • Atmospheric NLTE-models for the spectroscopic analysis of luminous blue stars with winds.
    We present a new, fast and easy to use NLTE line formation code for ``unified atmospheres'' with spherical extension and stellar winds, developed for the (routine) spectroscopic analysis of luminous blue stars, covering the spectral range from ``A'' to ``O'' and including central stars of planetary nebulae. The major features of our code are: Data

  • A New Chemo-evolutionary Population Synthesis Model for Early-Type Galaxies. II. Observations and Results
    We present the results of applying a new chemo-evolutionary stellar population model, developed in a previous paper, to new high-quality observational data of the nuclear regions of two representative elliptical galaxies and the bulge of the Sombrero galaxy. Here we fit in detail ~20 absorption lines and six optical and near-infrared colors

  • A Comparison Between Near-Infrared And Visible Imaging Of The Inner Coma Of Comet Hale-Bopp At Perihelion
    We present a comparison between images of comet C/1995 O1 (Hale-Bopp) obtained from 12 March to 9 May 1997, with two telescopes of the Observatorio del Teide (IAC, Tenerife, Spain) in visible (Johnson-V filter) and three near-infrared narrowband filters (Brγ (2.166 μm), CO (2.295 μm), and Kcon (2.260 μm)). No significant differences are observed

  • Time-Resolved Spectroscopy of RS CVn Short-Period Systems.I.CG CYG, BH VIR, and ER VUL
    We present the first results of our program of spectroscopic observations with orbital phase resolution of short-period active binaries. We have collected simultaneous data in the lines Hα, Hβ, and the infrared triplet (IRT) of Ca II (8498 and 8542 A). In this paper we discuss the methods used to analyze the spectra and describe the results

  • The orientation of WARPS in the Local Group.
    The three major spiral galaxies in the Local Group are known to be warped. The question is investigated of whether or not these three warps are aligned. Using available HI observations we find that they are noticeably aligned. Vectors defining the warp orientation form the following angles: [M 31, M 33]=33°; [M 31, Milky Way]=35°; [M 33, Milky Way]
