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... -
Companions to nearby stars from Pan-STARRS 1
We present the discovery of 57 wide (>5'') separation, low-mass (stellar and substellar) companions to stars in the solar neighborhood identified from Pan-STARRS 1 (PS1) data... -
Nearby M Dwarfs parameters
Comparisons between the planet populations around solar-type stars and those orbiting M dwarfs shed light on the possible dependence of planet formation and evolution on stellar... -
Parameters of NGC 5139 SGBs stars
{omega} Centauri is a peculiar globular cluster formed by a complex stellar population. To investigate it, we studied 172 stars belonging to the five SGBs that we can identify... -
Terzan 5 chemical and kinematical properties
As part of a study aimed at determining the kinematical and chemical properties of Terzan 5, we present the first characterization of the bulge stars surrounding this puzzling... -
Iron and alpha abundance of RGBs in M31 satellites
We present alpha to iron abundance ratios for 226 individual red giant branch stars in nine dwarf galaxies of the Andromeda (M31) satellite system. The abundances are measured... -
Very metal-poor stars in the Milky Way's halo
We explore the kinematics and orbital properties of a sample of 323 very metal-poor stars in the halo system of the Milky Way, selected from the high-resolution spectroscopic... -
SAGA: Stromgren survey of seismic KIC stars
Asteroseismology has the capability of precisely determining stellar properties that would otherwise be inaccessible, such as radii, masses, and thus ages of stars. When... -
Lithium abundances of a large sample of red giants
The lithium abundances for 378 G/K giants are derived with non-local thermodynamic equilibrium correction considered. Among these are 23 stars that host planetary systems. The... -
High quality Spitzer/MIPS obs. of F4-K2 stars
We present a Spitzer MIPS study of the decay of debris disk excesses at 24 and 70{mu}m for 255 stars of types F4-K2. We have used multiple tests, including consistency between... -
HIRES radial velocity measurements
In this paper we search for distant massive companions to known transiting gas giant planets that may have influenced the dynamical evolution of these systems. We present new... -
Properties of Kepler multi-planet candidate systems
The planet occurrence rate for multiple stars is important in two aspects. First, almost half of stellar systems in the solar neighborhood are multiple systems. Second, the... -
Metallicities of RGB stars in dwarf galaxies
We present spectroscopic metallicities of individual stars in seven gas-rich dwarf irregular galaxies (dIrrs), and we show that dIrrs obey the same mass-metallicity relation as... -
Spectroscopic members of Segue 2 galaxy
Segue 2, discovered by Belokurov et al. (2009, Cat. J/MNRAS/397/1748), is a galaxy with a luminosity of only 900L_{sun}. We present Keck/DEIMOS spectroscopy of 25 members of... -
Kinematics of halo red giants
We explore the kinematics and orbital properties of a sample of red giants in the halo system of the Milky Way that are thought to have formed in globular clusters based on... -
RVs and [Fe/H] of star members of NGC 6388
By combining high spatial resolution and wide-field spectroscopy performed, respectively, with SINFONI and FLAMES at the ESO/VLT we measured the radial velocities of more than... -
Kinematic analysis of red giant in M31 dSphs
We present a homogeneous kinematic analysis of red giant branch stars within 18 of the 28 Andromeda dwarf spheroidal (dSph) galaxies, obtained using the Keck I/LRIS and Keck... -
Improved stellar parameters of smallest KIC stars
We use the optical and near-infrared photometry from the Kepler Input Catalog to provide improved estimates of the stellar characteristics of the smallest stars in the Kepler... -
RR Lyrae stars BV photometry in UMa I
We have performed the first study of the variable star population of Ursa Major I (UMa I), an ultra-faint dwarf satellite recently discovered around the Milky Way (MW) by the...
