The [alpha/Fe] ratios of very metal-poor stars within the IGIMF theory
S. Recchi, F. Calura, B. K. Gibson +1
The aim of this paper is to quantify the amplitude of the predicted plateau in [alpha/Fe] ratios associated with the most metal-poor stars of a galaxy. We assume that the initial m…
In the thick of it: metal-poor disc stars in RAVE
G. Kordopatis, G. Gilmore, R. F. G. Wyse +17
By selecting in the RAVE-DR4 survey the stars located between 1 and 2 kpc above the Galactic plane, we question the consistency of the simplest three-component model (thin disc, th…
A new stellar chemo-kinematic relation reveals the merger history of the Milky Way disc
I. Minchev, C. Chiappini, M. Martig +27
The velocity dispersions of stars near the Sun are known to increase with stellar age, but age can be difficult to determine so a proxy like the abundance of alpha elements (e.g.,…
Chemical gradients in the Milky Way from the RAVE data. I. Dwarf stars
C. Boeche, A. Siebert, T. Piffl +20
Aim: We aim at measuring the chemical gradients of the elements Mg, Al, Si, and Fe along the Galactic radius to provide new constraints on the chemical evolution models of the Gala…
Diffuse interstellar band at 8620 Å in RAVE: A new method for detecting the diffuse interstellar band in spectra of cool stars
J. Kos, T. Zwitter, E. K. Grebel +16
Diffuse interstellar bands are usually observed in spectra of hot stars, where interstellar lines are rarely blended with stellar ones. The need for hot stars is a strong limitatio…
The RAVE survey: the Galactic escape speed and the mass of the Milky Way
T. Piffl, C. Scannapieco, J. Binney +22
We construct new estimates on the Galactic escape speed at various Galactocentric radii using the latest data release of the Radial Velocity Experiment (RAVE DR4). Compared to prev…
Constraints on the Galactic Bar from the Hercules stream as traced with RAVE across the Galaxy
T. Antoja, A. Helmi, W. Dehnen +20
Non-axisymmetries in the Galactic potential (spiral arms and bar) induce kinematic groups such as the Hercules stream. Assuming that Hercules is caused by the effects of the Outer…
The asymmetric drift, the local standard of rest, and implications from RAVE data
O. Golubov, A. Just, O. Bienaymé +13
The determination of the LSR is still a matter of debate. The classical value of the tangential peculiar motion of the Sun with respect to the LSR was challenged in recent years, c…
The Lowest Metallicity Stars in the LMC: Clues from MaGICC Simulations
Chris B. Brook, Maider S. Miranda, Brad. K. Gibson +2
Using a cosmological hydrodynamical simulation of a galaxy of similar mass to the Large Magellanic Cloud (LMC), we examine the predicted characteristics of its lowest metallicity p…
Galactic Constraints on Supernova Progenitor Models
I. Acharova, B. Gibson, Yu. Mishurov +1
We undertake a statistical analysis of the radial abundance distributions in the Galactic disk within a theoretical framework for Galactic chemical evolution which incorporates the…
Decoding the message from meteoritic stardust silicon carbide grains
Karen M. Lewis, Maria Lugaro, Brad K. Gibson +1
Micron-sized stardust grains that originated in ancient stars are recovered from meteorites and analysed using high-resolution mass spectrometry. The most widely studied type of st…
The relation between chemical abundances and kinematics of the Galactic disc with RAVE
C. Boeche, C. Chiappini, I. Minchev +20
Aims: We study the relations between stellar kinematics and chemical abundances of a large sample of RAVE giants in search for selection criteria needed for disentangling different…
