Abstract:
The structural parameters of the Large Magellanic Cloud and
the Small Magellanic Cloud are derived from the study of di
erent stellar
populations, such as, Cepheids (age
100 Myr), Red Clump stars (age
2-9 Gyr) and RR Lyrae stars (age
>
9 Gyr). The structural changes of
these galaxies as a function of time are identified and the processes which
are responsible for these changes are discussed. The formation and early
evolution of these two galaxies are found to be di
erent.
