The DR14 APOGEE-TGAS catalogue: Precise chemo-kinematics in the extended solar vicinity
(Cambridge University Press, 2017)
A FIRST CONSTRAINT ON THE THICK DISK SCALE LENGTH: DIFFERENTIAL RADIAL ABUNDANCES IN K GIANTS AT GALACTOCENTRIC RADII 4, 8, AND 12 kpc
(IOP PUBLISHING LTD, 2011)
Based on high-resolution spectra obtained with the MIKE spectrograph on the Magellan telescopes, we present detailed elemental abundances for 20 red giant stars in the outer Galactic disk, located at Galactocentric distances ...
Effects of the selection function on metallicity trends in spectroscopic surveys of the Milky Way
(EDP SCIENCES S A, 2017)
Context. Large spectroscopic Galactic surveys imply a selection function in the way they performed their target selection.
The Gaia-ESO Survey: a quiescent Milky Way with no significant dark/stellar accreted disc(a similar to...)
(OXFORD UNIV PRESS, 2015)
According to our current cosmological model, galaxies like the Milky Way are expected to experience many mergers over their lifetimes. The most massive of the merging galaxies will be dragged towards the disc plane, ...
Chemical similarities between Galactic bulge and local thick disk red giant stars
(EDP SCIENCES S A, 2008)
Context. The evolution of the Milky Way bulge and its relationship with the other Galactic populations is still poorly understood. The bulge has been suggested to be either a merger-driven classical bulge or the product ...
Mass density and size estimates for spiral galaxies using general relativity
(Springer, 2017)
Rotation curves of spiral galaxies reveal a physical phenomenon that has been seen to lack a satisfactory scientific explanation: velocities of stars far from the nucleus are high and approximately constant. In the context ...
New constraints on the chemical evolution of the solar neighbourhood and Galactic disc(s) Improved astrophysical parameters for the Geneva-Copenhagen Survey
(EDP SCIENCES S A, 2011)
We present a re-analysis of the Geneva-Copenhagen survey, which benefits from the infrared flux method to improve the accuracy of the derived stellar effective temperatures and uses the latter to build a consistent and ...
Kinematic analysis and membership status of TWA22 AB
(EDP SCIENCES S A, 2009)
Context. TWA22 was initially regarded as a member of the TW Hydrae association (TWA). In addition to being one of the youngest (approximate to 8 Myr) and nearest (approximate to 20 pc) stars to Earth, TWA22 has proven to ...
OXYGEN ABUNDANCES IN LOW- AND HIGH-alpha FIELD HALO STARS AND THE DISCOVERY OF TWO FIELD STARS BORN IN GLOBULAR CLUSTERS
(IOP PUBLISHING LTDBRISTOL, 2012)
Oxygen abundances of 67 dwarf stars in the metallicity range -1.6 < [Fe/H] < -0.4 are derived from a non-LTE analysis of the 777 nm O I triplet lines. These stars have precise atmospheric parameters measured by Nissen ...
