Investigating the halo of the LMC.

Recent results have shown that Long-Period Variables (LPVs) with periods in the range 100 to 250 days have ages about 10 Gyr. The kinematics of a sample of such variables in the LMC is studied. A comparison with the kinematics of other populations indicates that all populations younger than the old LPVs are dominated by a single common rotating disk, with the kinematics of the old LPVs being the first to indicate the presence in the LMC of a spheroidal population, with little or no rotation and a velocity dispersion about 6 times larger than that of the H I gas.
