Salviander, University of Texas at Austin abstract Double-Barred Galaxies in N-body Simulations Juntai Shen, University of Texas at Austin abstract At least one quarter of barred galaxies have secondary bars that are embedded in their large-scale primary counterparts. The dynamics of such double barred galaxies is still not well understood. We use collisionless N-body simulations to study the formation of double-barred galaxies. We will discuss the dynamical origins stability and the evolution of double bars formed in our simulation. The Extended Structure of the Leo II dSph Galaxy Michael H.
