KPNO spectroscopy of G & K dwarfs HIP stars
The tension between the Hipparcos parallax of the Pleiades and other independent distance estimates continues even after the new reduction of the Hipparcos astrometric data and... -
SpeX NIR survey of 886 nearby M dwarfs
We present a catalog of near-infrared (NIR) spectra and associated measurements for 886 nearby M dwarfs. The spectra were obtained with the NASA-Infrared Telescope Facility SpeX... -
Kepler planetary candidates. V. 3yr Q1-Q12
The Kepler mission discovered 2842 exoplanet candidates with 2yr of data. We provide updates to the Kepler planet candidate sample based upon 3yr (Q1-Q12) of data. Through a... -
Cool KOIs. VI. H- and K- band spectra
We present H- and K-band spectra for late-type Kepler Objects of Interest (the "Cool KOIs"): low-mass stars with transiting-planet candidates discovered by NASA's Kepler Mission... -
UBVRIJHK color-temperature calibration
A collection of Johnson/Cousins photometry for stars with known [Fe/H] is used to generate color-color relations that include the abundance dependence. Literature temperature... -
Abundances in stars of Milky Way dwarf satellites
We present a catalog of Fe, Mg, Si, Ca, and Ti abundances for 2961 stars in eight dwarf satellite galaxies of the Milky Way (MW): Sculptor, Fornax, Leo I, Sextans, Leo II, Canes... -
[Fe/H] and Teff for luminosity class IV-V stars
In this paper, an updated catalog containing averaged values of [Fe/H] is presented for FGK stars on and near the main sequence. The input data for the catalog are values of... -
SNR 0509-67.5 surviving companion search
The community agrees that Type Ia Supernovae (SNe Ia) arise from C/O white dwarfs undergoing thermonuclear runaway. However, the full progenitor system and the process that... -
Very metal-poor stars with LAMOST & Subaru. I.
The chemical abundances of very metal-poor stars provide important constraints on the nucleosynthesis of the first generation of stars and early chemical evolution of the... -
Metallicity of Gal. RRLyrae from opt & IR LCs. II.
We present new period-{phi}31-[Fe/H] relations for first-overtone RRL stars (RRc), calibrated over a broad range of metallicities (-2.5<~[Fe/H]<~0.0) using the largest... -
NIR light curves of type II Cepheids
We present time-series photometry of 21 nearby type II Cepheids in the near-infrared J, H, and Ks passbands. We use this photometry, together with the Third Gaia Early Data... -
K2 Galactic Archaeology Program DR3, final release
We present the third and final data release of the K2 Galactic Archaeology Program (K2 GAP) for Campaigns C1-C8 and C10-C18. We provide asteroseismic radius and mass... -
GC intrinsic iron abund. spreads. II. Milky Way
Intrinsic iron abundance spreads in globular clusters (GCs), although usually small, are very common, and are signatures of self-enrichment: some stars within the cluster have... -
Metallicities of very low metal-poor stars
This work presents a first attempt to apply fuzzy cluster analysis (FCA) to analyzing stellar spectra. FCA is adopted to categorize line indices measured from LAMOST... -
Kinematics of Ant2 & Cra2 with S5 (DR2.2) & Gaia data
We present new spectroscopic observations of the diffuse Milky Way satellite galaxies Antlia 2 and Crater 2, taken as part of the Southern Stellar Stream Spectroscopic Survey... -
Compilation of Cepheids in the MW and MCs
The Cepheid period-luminosity (PL) relation is the key tool for measuring astronomical distances and for establishing the extragalactic distance scale. In particular, the local... -
Kepler and XMM LCs of 3 KIC stars with flares
Solar and stellar flares are powerful events that produce intense radiation across the electromagnetic spectrum. Multiwavelength observations are highly important for... -
Metallicity of Gal. RR Lyrae from opt. & IR LCs
We present newly calibrated period-{phi}31-[Fe/H] relations for fundamental-mode RR Lyrae stars in the optical and, for the first time, mid-infrared. This work's calibration... -
Spectroscopic obs. in ATLAS and Aliqa Uma streams
We present the first spectroscopic measurements of the ATLAS and Aliqa Uma streams from the Southern Stellar Stream Spectroscopic Survey (S5), in combination with the... -
Planets Across Space and Time (PAST). I.
Over 4000 exoplanets have been identified and thousands of candidates are to be confirmed. The relations between the characteristics of these planetary systems and the...
