  • Spectroscopic and photometric evidence of two stellar populations in the Galactic globular cluster NGC 6121 (M 4)

    Aims: We present abundance analysis based on high resolution spectra of 105 isolated red giant branch (RGB) stars in the Galactic Globular Cluster NGC 6121 (M 4). Our aim is to study its star population in the context of the multi-population phenomenon recently discovered to affect some Globular Clusters. Methods: The data have been collected with

  • Spectroscopic Classification of Late-M and L Field Dwarfs

    We present spectra for 12 new ultracool dwarfs found in the DENIS infrared survey. Seven of them have spectral types at the bottom of the M-class (M8-M9.5), and the other five belong to the cooler ``L'' class. We also present spectra for the two new L dwarfs found by the EROS 2 proper-motion survey. We introduce a scheme for L dwarf classification

  • Spectroscopic classification of X-ray selected stars in the rho Ophiuchi star-forming region and vicinity

    We present intermediate-resolution (FWHM~1.5-2.6 Angstroms) optical spectra of 106 candidate optical counterparts of 77 X-ray sources detected in four pointed (t_exp>=8700 s) ROSAT PSPC observations of the rho Ophiuchi star-forming region and vicinity. Using the spectral types and equivalent widths of Hα and Liilambda670.8 nm obtained from our

  • Spectroscopic parameters for a sample of metal-rich solar-type stars

    Aims.To date, metallicity is the only parameter of a star that appears to clearly correlate with the presence of planets and their properties. To check for new correlations between stars and the existence of an orbiting planet, we determine accurate stellar parameters for several metal-rich solar-type stars. The purpose is to fill the gap of the

  • Spectroscopic pilot study in the near infrared of a sample of star-forming galaxies at z = 2

    In this work we present the results of the spectroscopic analysis inthe near-infrared K band of a sample of 12 active star forminggalaxies at z ˜ 2. The sample was selected by using photometricredshifts, blue colors and large fluxes in the 24 μ m band ofMIPS/Spitzer. To analyze their physical properties we have computedtheir sizes, colors, stellar

  • Spectroscopy of Pluto at six longitudes, 380-930 nm

    We have obtained spectra of the Pluto-Charon pair (unresolved) in the wavelength range 380-930 nm with resolution ~450 at six roughly equally spaced longitudes. The data were taken in May and June, 2014, with the 4.2-m Isaac Newton Telescope at Roque de Los Muchachos Observatory in the Canary Islands, using the ACAM (auxiliary-port camera) in
