Photoelectric UBV from HK survey. II.
Photoelectric UBV photometry is presented for a sample of 165 stars drawn from the extension of the HK objective-prism/interference-filter survey of Beers, Preston and Shectman... -
UBV photometry from HK survey. I
Photoelectric photometry is presented for a sample of 139 halo stars drawn an extension of the HK (Ca II H & K lines) objective-prism survey of Beers, Preston and Shectmann... -
LAMOST K giants in Galactic halo substructures
We construct a large halo K-giant sample by combining the positions, distances, radial velocities, and metallicities of over 13000 LAMOST DR5 halo K giants with the Gaia DR2... -
Local stellar halo member stars from Gaia DR2 & LAMOST
Based on the second Gaia data release and spectroscopy from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope Data, we identified 20,089 halo stars kinematically and... -
Metal-poor star RAVE J093730.5-062655 abundances
A new moderately r-process-enhanced metal-poor star, RAVEJ093730.5-062655, has been identified in the Milky Way halo as part of an ongoing survey by the R-Process Alliance. The... -
Galactic halo with APOGEE. II. Abundances.
The formation processes that led to the current Galactic stellar halo are still under debate. Previous studies have provided evidence for different stellar populations in terms... -
Abundances of two very metal-poor stars
From high resolution (R~=45000), high signal-to-noise ratio (S/N>400) spectra gathered with the Immersion Grating Infrared Spectrograph (IGRINS) in the H and K photometric... -
Highly likely members of the Sgr stream
Wrapping around the Milky Way, the Sagittarius stream is the dominant substructure in the halo. Our statistical selection method has allowed us to identify 106 highly likely... -
Detailed abundances for 97 metal-poor stars
we present the abundance analysis of 97 nearby metal-poor (-3.3<[Fe/H]<-0.5) stars having kinematic characteristics of the Milky Way (MW) thick disk and inner and outer... -
MW halo. III. Statistical chemical abundances
We find that the relative contribution of satellite galaxies accreted at high redshift to the stellar population of the Milky Way's smooth halo increases with distance, becoming... -
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... -
Fe and P abundances in 163 halo stars with HPF
Phosphorus (P) is a critical element for life on Earth, yet the cosmic production sites of P are relatively uncertain. To understand how P has evolved in the solar neighborhood,... -
NGC 1261 and NGC 1904 potential members
As globular clusters (GCs) orbit the Milky Way, their stars are tidally stripped forming tidal tails that follow the orbit of the cluster around the Galaxy. The morphology of... -
U Equ spectra and multi-photometry
U Equ is an unusual maser-hosting infrared source discovered in the 1990s. It was tentatively classified as a post-asymptotic giant branch (post-AGB) star with a unique optical... -
High-precision abundance of the Helmi streams
The Helmi streams are a kinematic substructure whose progenitor is likely a dwarf galaxy. Although 20 years have passed since their discovery, it is still unclear whether their... -
High-precision chemical abundances of Sequoia
Sequoia is a retrograde kinematic substructures in the nearby Galactic halo, whose properties are a matter of debate. For example, previous studies do not necessarily agree on... -
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...
