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.,…
The RAdial Velocity Experiment (RAVE): Fourth data release
G. Kordopatis, G. Gilmore, M. Steinmetz +48
We present the stellar atmospheric parameters (effective temperature, surface gravity, overall metallicity), radial velocities, individual abundances and distances determined for 4…
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…
Dynamics for Galactic Archaeology
James Binney
Our Galaxy is a complex machine in which several processes operate simultaneously: metal-poor gas is accreted, is chemically enriched by dying stars, and then drifts inwards, surre…
Dynamical models and Galaxy surveys
James Binney, Jason L Sanders
Equilibrium dynamical models are essential tools for extracting science from surveys of our Galaxy. We show how models can be tested with data from a survey before the survey's sel…
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…
Galactic kinematics and dynamics from RAVE stars
James Binney, Ben Burnett, Georges Kordopatis +15
We analyse the kinematics of ~400000 RAVE stars. We split the sample into hot and cold dwarfs, red-clump and non-clump giants. The kinematics of the clump giants are consistent wit…
New distances to RAVE stars
James Binney, Ben Burnett, Georges Kordopatis +16
Probability density functions are determined from new stellar parameters for the distance moduli of stars for which the RAdial Velocity Experiment (RAVE) has obtained spectra with…
Stream-orbit misalignment II: A new algorithm to constrain the Galactic potential
Jason L. Sanders, James Binney
In the first of these two papers we demonstrated that assuming streams delineate orbits can lead to order one errors in potential parameters for realistic Galactic potentials. Moti…
Stream-orbit misalignment I: The dangers of orbit-fitting
Jason L. Sanders, James Binney
Tidal streams don't, in general, delineate orbits. A stream-orbit misalignment is expected to lead to biases when using orbit-fitting to constrain models for the Galactic potential…
Analysing surveys of our Galaxy -- II. Determining the potential
Paul J. McMillan, James J. Binney
We consider the problem of determining the Galaxy's gravitational potential from a star catalogue. We show that orbit-based approaches to this problem suffer from unacceptable nume…
Ionized absorbers as evidence for supernova-driven cooling of the lower Galactic corona
Filippo Fraternali, Antonino Marasco, Federico Marinacci +1
We show that the ultraviolet absorption features, newly discovered in HST spectra, are consistent with being formed in a layer that extends a few kpc above the disk of the Milky Wa…
