die Natur der Dicken Scheibe unserer
This thesis consideres different scenarios
for the formation of the thick disk in our Milky Way. There are generally
two families of creation hypotheses. The first group consideres the thick
disk as separate entity produced in an early phase of the initial protogalactic
collaps. The second set of models sees the thick disk as extension of the
thin disk formed via some heating mechanism acting on the thin disk star
population (and therefore formed somehow later and through successively
Using Galactic globular clusters, I can derive constraints on different thick disk heating szenarios, which rule out all but one: heating by infalling (accreting) satellite galaxies.
