    The chemical composition of Galactic ring nebulae around massive stars
    We present deep spectra of ring nebulae associated with Wolf-Rayet (WR) and O-type stars: NGC 6888, G2.4+1.4, RCW 58, S 308, NGC 7635 and RCW 52. The data have...

    The chemical composition of HII regions in the outer Galaxy
    New spectroscopic observations, including the optical and near-infrared ranges, have been obtained for a sample of HII regions located towards the Galactic...

    The chemical composition of the post-asymptotic giant branch F supergiant CRL 2688
    We present an analysis of a high-resolution (R ˜ 50 000) optical spectrum of the central region of the protoplanetary nebula CRL 2688. This object is thought to...

    The chemical compositions of accreted and in situ galactic globular clusters according to SDSS/APOGEE
    Studies of the kinematics and chemical compositions of Galactic globular clusters (GCs) enable the reconstruction of the history of star formation, chemical...

    The chemical content of nearby galaxies from planetary nebulae: NGC 147
    We report the results of spectroscopic observations, obtained with the Gemini Multi-Object Spectrograph, of eight planetary nebulae (PNe) in the dwarf...

    The chemical evolution of dwarf spheroidal galaxies: dissecting the inner regions and their stellar populations
    Using three-dimensional hydrodynamical simulations of isolated dwarf spheroidal galaxies (dSphs), we undertake an analysis of the chemical properties of their...

    The chemical evolution of globular clusters - I. Reactive elements and non-metals
    We propose a new chemical evolution model aimed at explaining the chemical properties of globular clusters (GCs) stars. Our model depends upon the existence of...

    The chemo-dynamical groups of Galactic globular clusters
    We introduce a multicomponent chemo-dynamical method for splitting the Galactic population of globular clusters (GCs) into three distinct constituents: bulge...

    The CIDA-UCM-Yale shallow survey for emission-line galaxies
    We present the CIDA-UCM-Yale (Centro de Investigaciones de Astronomía, Universidad Complutense de Madrid, and Yale University) Survey (CUYS) for Hα+[NII] 6549...
