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/1959.14/305098
Description: Aims. We provide new constraints on the chemo-dynamical models of the Milky Way by measuring the radial and vertical chemical gradients for the elements Mg, Al, Si, Ti, and Fe in the Galactic disc and ... More

Identifier: http://hdl.handle.net/1959.14/337559
Description: We use the kinematics of similar to 200 000 giant stars that lie within similar to ~1.5 kpc of the plane to measure the vertical profile of mass density near the Sun. We find that the dark mass contai ... More

Identifier: http://hdl.handle.net/1959.14/308052
Description: We analyse the kinematics of ~400 000 stars that lie within ~2 kpc of the Sun and have spectra measured in the Radial Velocity Experiment. We decompose the sample into hot and cold dwarfs, red-clump a ... 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/1959.14/274760
Description: Diffuse interstellar bands (DIBs) 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 limitation in the numb ... More
