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/1959.14/306635
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/1959.14/304639
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/1959.14/304801
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

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
