  • Atlas of Synthetic Spectra

    A library of 711 cool star synthetic spectra in the wavelength range 485-540nm is presented. The coverage in the parameter space span in surface gravity from 1.0 to 5.0dex at a...
  • Spectroscopy of HD 45677 = MWC 142

    On the basis of spectroscopic CCD material obtained at the Haute Provence Observatory, we provide line identifications and equivalent width measurements in the wavelength...
  • RR Tel UV emission

    (no description available)
  • Ca II triplet lines in cool stars

    CCD spectra of the infrared triplet lines of ionized calcium at {lambda}{lambda}8498, 8542, 8662 have been obtained at a spectral resolution of 0.4{AA} in 146 stars brighter...
  • Late-type star spectra

    In this work we present spectroscopic observations centered in the spectral lines most widely used as optical indicators of chromospheric activity (H{alpha}, H{beta}, Ca II H...
  • Spectral classifications of 180 IR stars

    A sample of 180 supposedly composite-spectrum stars has been studied on the basis of spectra obtained in the near infrared (8370-8780{AA}) at a dispersion of 33{AA}/mm. The...
  • UV variability of Fairall-9

    This is a study of the UV variability of the galaxy Fairall-9 between 1978 and 1991. Table 1 shows the UV continuum fluxes measured in three "line-free" windows centered at...
  • Near-IR spectra of 7 Be stars and AG Car

    We present and discuss {lambda} 6470-8780 spectra of 7 poorly-studied Be stars and of one Luminous Blue Variable (AG Car), and give equivalent widths and radial velocities of...
  • Spectroscopy of MWC 645

    We analyse spectroscopic CCD material obtained at the Haute Provence Observatory. We provide identifications and equivalent width measurements in the wavelength region...
  • Long-slit spectroscopy of UCM galaxies

    Spectroscopic observations for the full sample of H{alpha} emission-line galaxy candidates (ELGs) from the Universidad Complutense de Madrid objective-prism survey Lists 1 and 2...
  • Ionized gas velocity in 6 galaxies

    We report observations of the velocity field of the ionized gas in the nearby ellipticals NGC 1453, NGC 2974, NGC 3962, NGC 4636, NGC 6868 and NGC 7097. This is part of an ESO...
  • Spectroscopy of MWC 349 A

    We analyse spectroscopic CCD material obtained at the Haute Provence Observatory. We provide line identifications and equivalent width measurements in the wavelength region...
  • Spectra of 21 late-type stars

    We present optical spectra of 21 stars from 4800 to 8920A, covering essentially the late spectral types, G, K, M and the luminosity classes I and III. Half of the stars are...
  • Spectroscopy of HD 51585 (= OY Gem)

    We analyse CCD spectroscopic material obtained at the Haute Provence Observatory between 1990 and 1993, covering the wavelength region 380-1100mm. 320 emission lines were...
  • Magellanic Clouds PNe line intensities

    We present optical and ultraviolet spectroscopic observations of planetary nebulae (PNe) in the Large (LMC) and the Small Magellanic Clouds (SMC). For the visible spectra with...
  • Variability in O-stars wind

    The tables below list the Log of IUE observations incorporated in the paper. The table number corresponds to the figure number in the paper. The involved O star and the...
  • H band stellar spectra

    A sample of 37 stars of luminosity classes I, III, V, including few SMR stars observed in the H band with a medium resolution (R=1500-2000) is presented. This sample of flux...
  • Spectral Atlas of P Cygni in range 4840-6760A

    Using the coude spectrograph of the NAO 2m RCC telescope at the Rhodope Mountains, Bulgaria, 11 spectra in the wavelength range from 4840 to 6760A of P Cygni were obtained...
  • Lines in the infrared solar spectrum

    We list 603 spectral lines between 1.0, 1.8um that are judged to be relatively unblended from a visual inspection of spectra of the quiet sun. Much of the atomic data of...
  • Ultraviolet Spectrum of the Sun

    An ultraviolet atlas of the solar spectrum with a spectral resolution of 15mA in the region 1948-2000A is presented. It is the first part of the spectra recorded on the quiet...
