Identifier: http://hdl.handle.net/1959.14/332014
Description: We aim to characterize high-velocity (HiVel) stars in the solar vicinity both chemically and kinematically using the fourth data release of the RAdial Velocity Experiment (RAVE). We used a sample of 5 ... More

Identifier: http://hdl.handle.net/1959.14/355466
Description: We study the kinematics of a local sample of stars, located within a cylinder of 500 pc radius centered on the Sun, in the RAVE data set. We find clear asymmetries in the VR-VΦ velocity distributions ... More

Identifier: http://hdl.handle.net/1959.14/355379
Description: Using the RAdial Velocity Experiment fourth data release (RAVE DR4), and a new metallicity calibration that will be also taken into account in the future RAVE DR5, we investigate the existence and the ... More

Identifier: http://hdl.handle.net/1959.14/306635
Description: 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 α elements (e.g., Mg) with respect to iro ... More

Identifier: http://hdl.handle.net/1959.14/326414
Description: We investigate the kinematic parameters of the Milky Way disk using the Radial Velocity Experiment (RAVE) and Geneva-Copenhagen Survey (GCS) stellar surveys. We do this by fitting a kinematic model to ... More

Identifier: http://hdl.handle.net/1959.14/304705
Description: We made new estimates of the Galactic escape speed at various Galactocentric radii using the latest data release of the RAdial Velocity Experiment (RAVE DR4). Compared to previous studies we have a da ... More

Identifier: http://hdl.handle.net/1959.14/271611
Description: By selecting in the Radial Velocity Experiment-fourth data release (RAVE-DR4) survey the stars located between 1 and 2 kpc above the Galactic plane, we question the consistency of the simplest three-c ... More

Identifier: http://hdl.handle.net/1959.14/217626
Description: Using the Radial Velocity Experiment (RAVE) survey, we recently brought to light a gradient in the mean galactocentric radial velocity of stars in the extended solar neighbourhood. This gradient likel ... More
