Identifier: http://hdl.handle.net/1959.14/1204790
Description: We report the identification of extended tidal debris potentially associated with the globular cluster NGC 3201, using the RAdial Velocity Experiment (RAVE) catalogue. We find the debris stars are loc ... More

Identifier: http://hdl.handle.net/1959.14/304639
Description: Context. Galactic open clusters (OCs) mainly belong to the young stellar population in the Milky Way disk, but are there groups and complexes of OCs that possibly define an additional level in hierarc ... 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/1959.14/304801
Description: 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 Lindblad resonance o ... More
