Evidence for Blue Straggler Stars Rejuvenating the Integrated Spectra of Globular Clusters
A. Javier Cenarro, J. L. Cervantes, Michael A. Beasley +2
Integrated spectroscopy is the method of choice for deriving the ages of unresolved stellar systems. However, hot stellar evolutionary stages, such as hot horizontal branch stars a…
A new stellar library in the region of the CO index at 2.3 m. New index definition and empirical fitting functions
E. Mármol-Queraltó, N. Cardiel, A. J. Cenarro +5
Context: The analysis of unresolved stellar populations demands evolutionary synthesis models with realistic physical ingredients and extended wavelength coverage. Aims: To obtain…
The relation between stellar populations, structure and environment for dwarf elliptical galaxies from the MAGPOP-ITP
D. Michielsen, A. Boselli, C. J. Conselice +9
Dwarf galaxies, as the most numerous type of galaxy, offer the potential to study galaxy formation and evolution in detail in the nearby Universe. Although they seem to be simple s…
Stellar populations of Globular Clusters in the Elliptical galaxy NGC1407
A. Javier Cenarro, Michael A. Beasley, Jay Strader +2
We present high-quality, Keck spectroscopic data for a sample of 20 globular clusters (GCs) in the massive E0 galaxy NGC1407. A subset of twenty line-strength indices of the Lick/I…
Medium-resolution Isaac Newton Telescope library of empirical spectra - II. The stellar atmospheric parameters
A. J. Cenarro, R. F. Peletier, P. Sanchez-Blazquez +7
We present a homogeneous set of stellar atmospheric parameters Teff, log g, [Fe/H] for MILES, a new spectral stellar library covering the range 3525 - 7500 angstrom at 2.3 angstrom…
A New Method for Isolating M31 Red Giant Stars: The Discovery of Stars out to a Radial Distance of 165 Kiloparsecs
Karoline M. Gilbert, Puragra Guhathakurta, Jasonjot S. Kalirai +8
We present a method for isolating a clean sample of red giant stars in the outerregions of the Andromeda spiral galaxy (M31) from an ongoing spectroscopic survey using the DEIMOS i…
