Such substructure, caused by stellar streams, is an important diagnostic of stellar dynamics and hierarchical formation of the Galaxy. While possibly phase-mixed, stellar streams remain detectable as coherent features in the space of integrals of motion. This thesis describes the development of new search techniques in phase- and [Fe\/H]-space to derive \"effective\" integrals of motion that are most suitable for a comparison with the observables. An application of these techniques to two new data sets which contain radial velocity- and proper motion estimates reveals significant \"phase-space overdensities\" of stars on similar orbits, of which some are already known, but at least five are described here for the first time. This thesis also outlines a preperatory study in the context of GAIA to measure the local gravitational potential on kpc scale.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838103884\"\u003e\u003ch3\u003eKinematic Studies of nearby Stars\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783838103884","offer_id":39456444153949,"sku":"9783838103884","price":79.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/2894c310-b2cf-4846-9afc-95ffb9f1c4cc.jpg?v=1773208474","url":"https:\/\/shop.autorenwelt.de\/products\/stellar-phase-space-structure-and-dynamics-in-the-solar-neighbourhood-kinematic-studies-of-nearby-stars-von-rainer-klement","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
