The Eighteenth Data Release of the Sloan Digital Sky Surveys: Targeting and First Spectra from SDSS-V
Andrés Almeida, Scott F. Anderson, Maria Argudo-Fernández +151
The eighteenth data release of the Sloan Digital Sky Surveys (SDSS) is the first one for SDSS-V, the fifth generation of the survey. SDSS-V comprises three primary scientific progr…
Final Targeting Strategy for the SDSS-IV APOGEE-2S Survey
Felipe A. Santana, Rachael L. Beaton, Kevin R. Covey +43
APOGEE is a high-resolution (R sim 22,000), near-infrared, multi-epoch, spectroscopic survey of the Milky Way. The second generation of the APOGEE project, APOGEE-2, includes an ex…
Final Targeting Strategy for the SDSS-IV APOGEE-2N Survey
Rachael L. Beaton, Ryan J. Oelkers, Christian R. Hayes +57
APOGEE-2 is a dual-hemisphere, near-infrared (NIR), spectroscopic survey with the goal of producing a chemo-dynamical mapping of the Milky Way Galaxy. The targeting for APOGEE-2 is…
Four Jovian planets around low-luminosity giant stars observed by the EXPRESS and PPPS
M. I. Jones, R. Wittenmyer, C. Aguilera-Gómez +12
We report the discovery of planetary companions orbiting four low-luminosity giant stars with M between 1.04 and 1.39 M. All four host stars have been independently…
A MegaCam Survey of Outer Halo Satellites. VII. A Single Sérsic Index v/s Effective Radius Relation for Milky Way Outer Halo Satellites
Sebastián Marchi-Lasch, Ricardo R. Muñoz, Felipe A. Santana +6
In this work we use structural properties of Milky Way's outer halo () satellites (dwarf spheroidal galaxies, ultra-faint dwarf galaxies and globular cluste…
A chemical and kinematical analysis of the intermediate-age open cluster IC 166 from APOGEE and Gaia DR2
J. Schiappacasse-Ulloa, B. Tang, J. G. Fernández-Trincado +26
IC 166 is an intermediate-age open cluster ( Gyr) which lies in the transition zone of the metallicity gradient in the outer disc. Its location, combined with our very limi…
A MegaCam Survey of Outer Halo Satellites. III. Photometric and Structural Parameters
Ricardo R. Munoz, Patrick Cote, Felipe A. Santana +5
We present structural parameters from a wide-field homogeneous imaging survey of Milky Way satellites carried out with the MegaCam imagers on the 3.6m Canada-France-Hawaii Telescop…
A MegaCam Survey of Outer Halo Satellites. I. Description of the Survey
Ricardo R. Munoz, Patrick Cote, Felipe A. Santana +5
We describe a deep, systematic imaging study of satellites in the outer halo of the Milky Way. Our sample consists of 58 stellar overdensities --- i.e., substructures classified as…
Stellar and Planetary Characterization of the Ross 128 Exoplanetary System from APOGEE Spectra
Diogo Souto, Cayman T. Unterborn, Verne V. Smith +14
The first detailed chemical abundance analysis of the M dwarf (M4.0) exoplanet-hosting star Ross 128 is presented here, based upon near-infrared (1.5--1.7 \micron) high-resolution…
Chemical Abundances of Main-Sequence, Turn-off, Subgiant and red giant Stars from APOGEE spectra I: Signatures of Diffusion in the Open Cluster M67
Diogo Souto, Katia Cunha, Verne V. Smith +21
Detailed chemical abundance distributions for fourteen elements are derived for eight high-probability stellar members of the solar metallicity old open cluster M67 with an age of…
A survey for dwarf galaxy remnants around fourteen globular clusters in the outer halo
A. Sollima, D. Martinez-Delgado, R. R. Munoz +6
We report the results of a systematic photometric survey of the peripheral regions of a sample of fourteen globular clusters in the outer halo of the Milky Way at distances d_GC>25…
H-band discovery of additional Second-Generation stars in the Galactic Bulge Globular Cluster NGC 6522 as observed by APOGEE and Gaia
José G. Fernández-Trincado, O. Zamora, Diogo Souto +34
We present elemental abundance analysis of high-resolution spectra for five giant stars, deriving Fe, Mg, Al, C, N, O, Si and Ce abundances, and spatially located within the innerm…
The Hercules stream as seen by APOGEE-2 South
Jason A. S. Hunt, Jo Bovy, Angeles Pérez-Villegas +15
The Hercules stream is a group of co-moving stars in the Solar neighbourhood, which can potentially be explained as a signature of either the outer Lindblad resonance (OLR) of a fa…
