Title:Orbit analysis of the dwarf galaxies with an application to Carina.

Abstract:
We present a new study of the evolution of the Carina dwarf galaxy that includes a simultaneous derivation 
of its orbit and star formation history. The structure of the galaxy is constrained through orbital parameters 
derived from the observed distance, proper motions, radial velocity and star formation history. The different 
orbits admitted by the large proper motion errors are investigated in relation to the tidal force exerted by an 
external potential representing the Milky Way (MW). Our analysis is performed with the aid of fully
consistent N-body simulations that are able to follow the dynamics and the stellar evolution of the dwarf 
system in order to determine self-consistently the star formation history of Carina. We find a star formation 
history characterized by several bursts, partially matching the observational expectation. We find also
compatible results between dynamical projected quantities and the observational constraints.
