Poster: Theory Group at Concepcion

Michael Fellhauer

Abstract
In this poster we review three small projects performed in the theory group in 
Concepcion namely:
1) Ursa Major II - How much dark matter?: New models of UMaII giving up the 
connection with the Orphan stream. Our models show that it is possible to reproduce 
the dwarf dynamically starting from an extented star cluster.
2) Popping star clusters as building blocks of the MW Thick disc: We show that we 
can reproduce the properties of the thin and the thick disc component by dissolving 
star clusters due to gas-expulsion. We find two new interesting effects called 
Christmas-tree and azimuthal fish.
3) Dynamical mass of the dwarf galaxy pair Leo IV & V: We show which mass is 
required if we assume that Leo IV and Leo V are forming a tightly bound pair and 
compare with observations.
