A comprehensive view of Virgo stellar stream
To explore the complex halo substructure that has been reported in the direction of the Virgo constellation, radial velocities and metallicities have been measured for 82 RR... -
Halo red giants from the SEGUE survey
We present a spectroscopic search for halo field stars that originally formed in globular clusters. Using moderate-resolution SDSS-III/SEGUE-2 spectra of 561 red giants with... -
Extremely metal-poor turnoff stars abundances
The detailed chemical abundances of extremely metal-poor (EMP) stars are key guides to understanding the early chemical evolution of the Galaxy. Most existing data, however,... -
Yields from extremely metal-poor stars
The growing body of spectral observations of the extremely metal-poor (EMP) stars in the Galactic Halo provides constraints on theoretical studies of the chemical and stellar... -
FeII, ZNI and SI abundances on halo stars
The table gives equivalent widths (in m{AA}) for 19 FeII lines, two ZnI lines, and four SI lines, as measured in high resolution VLT/UVES spectra of 34 metal-poor, main sequence... -
Extremely metal-poor giants equivalent widths
This paper reports detailed abundance analyses for four extremely metal-poor (XMP) giant stars with [Fe/H]<-3.8, based on high-resolution, high- S/N spectra from the ESO VLT... -
Action-space clustering on stellar stream data
Stream stars removed by tides from their progenitor satellite galaxy or globular cluster act as a group of test particles on neighbouring orbits, probing the gravitational field... -
Carbon-enhanced metal-poor stars
We revisit the observed frequencies of carbon-enhanced metal-poor (CEMP) stars as a function of the metallicity in the Galaxy, using data from the literature with available... -
Galactic halo as seen by the CFHTLS
We use Canada-France-Hawaii Telescope Legacy Survey data for 170deg^2^, recalibrated and transformed to the Sloan Digital Sky Survey ugri photometric system, to study the... -
Velocities of blue stars near (l,b)=(198,-27)
We present evidence for a ring of stars in the plane of the Milky Way, extending at least from l=180{deg} to 227{deg} with turnoff magnitude g~19.5; the ring could encircle the... -
UBV photometry of AB stars in halo
The results of photoelectric UBV photometry of 234 AB stars in the southern galactic halo are presented. The stars were chosen from the Curtis Schmidt objective-prism survey of... -
Stellar halo of NGC 5128 (Centaurus A)
The extended stellar halos of galaxies contain important clues for investigating their assembly history and evolution. We investigate the resolved stellar content and the... -
Cool carbon stars in the halo and Fornax dSph
The population of cool carbon (C) stars located far from the galactic plane is probably made of debris of small galaxies such as the Sagittarius dwarf spheroidal galaxy (Sgr),... -
723 Gaia DR2 White dwarfs cand. in Local Galactic Halo
We present a catalog of 531 white dwarf candidates that have large apparent transverse motions relative to the Sun (v_T_>200km/s), thus making them likely members of the... -
Candidate halo wide binaries
We present an improved catalog of halo wide binaries compiled from an extensive literature search. Most of our binaries stem from the common proper motion binary catalogs by... -
Stellar density map of the Milky Way
We map the stellar structure of the Galactic thick disk and halo by applying color-magnitude diagram (CMD) fitting to photometric data from the Sloan Extension for Galactic... -
Spaghetti Survey
The Spaghetti project is a pencil-beam photometric and spectroscopic survey designed to identify structure in the Galactic halo. Four-color stellar photometry in the modified...
