资源简介:
A number of high-precision proper motion programs utilizing HST have already been used to study different aspects of the Magellanic Cloud system comma thereby having a tremendous impact on our understanding of this pair of interacting galaxies and its relation to the Milky Way. It has been shown that both Clouds move much faster than previously assumed comma suggesting they are most likely on a first passage around the Milky Way. Also comma the internal rotation pattern of the Large Magellanic Cloud (LMC) in the plane of the sky has been revealed for the first time using data from HST. However comma to date little is known about the dynamics of the star-cluster system within the LMC. To eliminate this lack of knowledge comma we propose here for an additional epoch of HST observations for a sample of 19 massive LMC star clusters that span a wide range of ages and galactocentric distances to get comma for the first time comma a precise measurement of the clusters. proper motions. This program aims to use star clusters as tracers to probe the gravitational potential of the LMC comma to study the kinematic pattern of the LMC as traced by star clusters at various ages and also to place important constraints on the interaction history of the Magellanic Cloud system.
