A spectroscopic quadruple as a possible progenitor of sub-Chandrasekhar Type Ia supernovae
T. Merle, A. S. Hamers, S. Van Eck +13
Binaries have received much attention as possible progenitors of Type Ia supernova (SNIa) explosions, but long-term gravitational effects in tight triple or quadruple systems could…
The Gaia-ESO survey: impact of extra-mixing on C- and N-abundances of giant stars
N. Lagarde, C. Reylé, A. C. Robin +30
The GES survey using FLAMES at the VLT has obtained high-resolution UVES spectra for a large number of giant stars, allowing a determination of the abundances of the key chemical e…
The selection function of the RAVE survey
Jennifer Wojno, Georges Kordopatis, Tilmann Piffl +23
We characterize the selection function of RAVE using 2MASS as our underlying population, which we assume represents all stars which could have potentially been observed. We evaluat…
The RAVE-on catalog of stellar atmospheric parameters and chemical abundances for chemo-dynamic studies in the Gaia era
Andrew R. Casey, Keith Hawkins, David W. Hogg +24
The orbits, atmospheric parameters, chemical abundances, and ages of individual stars in the Milky Way provide the most comprehensive illustration of galaxy formation available. Th…
The Cannon 2: A data-driven model of stellar spectra for detailed chemical abundance analyses
Andrew R. Casey, David W. Hogg, Melissa Ness +3
We have shown that data-driven models are effective for inferring physical attributes of stars (labels; Teff, logg, [M/H]) from spectra, even when the signal-to-noise ratio is low.…
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…
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…
A constant dark matter halo surface density in galaxies
F. Donato, G. Gentile, P. Salucci +6
We confirm and extend the recent finding that the central surface density r_0*rho_0 galaxy dark matter halos, where r_0 and rho_0 are the halo core radius and central density, is n…
The Fifth Data Release of the Sloan Digital Sky Survey
Jennifer K. Adelman-McCarthy
This paper describes the Fifth Data Release (DR5) of the Sloan Digital Sky Survey (SDSS). DR5 includes all survey quality data taken through June 2005 and represents the completion…
The Radial Velocity Experiment (RAVE): first data release
M. Steinmetz, T. Zwitter, A. Siebert +51
We present the first data release of the Radial Velocity Experiment (RAVE), an ambitious spectroscopic survey to measure radial velocities and stellar atmosphere parameters (temper…
