On the C and N Abundances of 47 Tucanae Main Sequence Stars
Michael M. Briley, Daniel Harbeck, Graeme H. Smith +1
We report the results of an analysis of CN and CH band strengths among a large sample of 47 Tucanae main-sequence and turn-off stars presented earlier by Harbeck et al. The resulti…
Low-Surface-Brightness Galaxies in the Sloan Digital Sky Survey. I. Search Method and Test Sample
Alexei Y. Kniazev, Eva K. Grebel, Simon A. Pustilnik +4
In this paper we present results of a pilot study to use imaging data from the Sloan Digital Sky Survey (SDSS) to search for low-surface-brightness (LSB) galaxies. For our pilot st…
The near-IR properties and continuum shapes of high redshift quasars from the Sloan Digital Sky Survey
Laura Pentericci, Hans W. Rix, Francisco Prada +7
We present J-H-K' photometry for a sample of 45 high redshift quasars found by the Sloan Digital Sky Survey. The sample was originally selected on the basis of optical colors and s…
CN Variations in NGC 7006
Daniel Harbeck, Graeme H. Smith, Eva K. Grebel
Rotationally induced mixing with subsequent dredge-up of nucleosynthesized material is discussed as a second parameter of the horizontal branch morphology in globular clusters. CNO…
The First Data Release of the Sloan Digital Sky Survey
The SDSS collaboration, Kevork Abazajian
The Sloan Digital Sky Survey has validated and made publicly available its First Data Release. This consists of 2099 square degrees of five-band (u, g, r, i, z) imaging data, 186,2…
Draco -- A Failure of the Tidal Model
Ralf Klessen, Eva Grebel, Daniel Harbeck
We test whether the structural properties of the nearby dwarf spheroidal (dSph) galaxy Draco, a well-studied Milky Way companion, can be reconciled with the suggestion that dSphs a…
