Star clusters in M31. VII. Globular clusters RVs
We carry out a joint spatial-kinematical-metallicity analysis of globular clusters (GCs) around the Andromeda Galaxy (M31), using a homogeneous, high-quality spectroscopic data... -
LOS velocities & [Fe/H] of Pal 5 tidal stream
We present Subaru/Faint Object Camera and Spectrograph and Keck/Deep Imaging Multi-Object Spectrometer medium-resolution spectroscopy of a tidally disrupting Milky Way (MW)... -
Magellan/M2FS spectroscopy of Tucana 2 and Grus 1
We present results from spectroscopic observations with the Michigan/Magellan Fiber System (M2FS) of 147 stellar targets along the line of sight to the newly discovered... -
MEarth photometry: nearby M-dwarf magnitudes
The MEarth Project is a photometric survey systematically searching the smallest stars near the Sun for transiting rocky planets. Since 2008, MEarth has taken approximately two... -
The SEGUE K giant survey. III. Galactic halo
We statistically quantify the amount of substructure in the Milky Way stellar halo using a sample of 4568 halo K giant stars at Galactocentric distances ranging over 5-125kpc.... -
Kepler multiple transiting planet systems
The Kepler mission provides a wealth of multiple transiting planet systems (MTPSs). The formation and evolution of multi-planet systems are likely to be influenced by companion... -
Machine learning metallicity predictions using SDSS
Extremely metal-poor (EMP) stars ([Fe/H]<=-3.0dex) provide a unique window into understanding the first generation of stars and early chemical enrichment of the universe. EMP... -
Stellar and planet properties for K2 candidates
The extended Kepler mission, K2, is now providing photometry of new fields every three months in a search for transiting planets. In a recent study, Foreman-Mackey and... -
Spectroscopy of Reticulum II
We present Magellan/M2FS, Very Large Telescope/GIRAFFE, and Gemini South/GMOS spectroscopy of the newly discovered Milky Way satellite Reticulum II. Based on the spectra of 25... -
The Cannon: a new approach to determine abundances
New spectroscopic surveys offer the promise of stellar parameters and abundances ("stellar labels") for hundreds of thousands of stars; this poses a formidable spectral modeling... -
M2FS stellar spectroscopy of Reticulum 2
We present results from spectroscopic observations with the Michigan/Magellan Fiber System (M2FS) of 182 stellar targets along the line of sight (LOS) to the newly discovered... -
Properties of 70 RR Lyrae stars in the LMC bar
We present results of the analysis of 70 RR Lyrae stars located in the bar of the Large Magellanic Cloud (LMC). Combining the spectroscopically determined metallicity of these... -
Metallicity of RGB stars in 6 M31 dwarf galaxies
We present global metallicity properties, metallicity distribution functions (MDFs), and radial metallicity profiles for the six most luminous M31 dwarf galaxy satellites: M32,... -
Abundances from SEGUE Stellar Parameters Pipeline
A fundamental challenge for wide-field imaging surveys is obtaining follow-up spectroscopic observations: there are >10^9^ photometrically cataloged sources, yet modern... -
Abundances of late-type stars
We report the detection of several absorption lines of neutral phosphorus (P, Z=15) in archival near-ultraviolet spectra obtained with the Space Telescope Imaging Spectrograph... -
AGB and RGB stars in 47 Tuc
We present the iron abundance of 24 asymptotic giant branch (AGB) stars, members of the globular cluster 47 Tucanae, obtained with high-resolution spectra collected with the... -
Chemical properties of M31 star clusters
We present ages, [Fe/H] and abundances of the {alpha} elements CaI, SiI, TiI, TiII, and light elements MgI, NaI, and AlI for 31 globular clusters (GCs) in M31, which were... -
Red giant star sample from SDSS
We have obtained a sample of ~22000 red giant branch (RGB) stars based on stellar parameters, provided by the ninth data release of the Sloan Digital Sky Survey (Cat. V/139),... -
Iron abundance of Terzan 5 stars
We present new determinations of the iron abundance for 220 stars belonging to the stellar system Terzan 5 in the Galactic bulge. The spectra have been acquired with FLAMES at... -
SDSS RGB stars distances
We present distance determinations for a large and clean sample of red giant branch stars selected from the ninth data release of the Sloan Digital Sky Survey (Adelman-McCarthy...
