Using the virial theorem: the mass of a cluster of galaxies

WebbThe average value of the 1-D velocity squared -- in the radial direction -- is Now, if the motions of the stars in the cluster are isotropic, then there is nothing special about the direction towards Earth; that means that the true, 3-D velocities of the stars in the cluster have an average squared value WebbThere are several reasons for this. In small open clusters, the average speed of the member stars within the cluster may be higher than the cluster’s escape velocity, 1 and the stars will gradually “evaporate” from the cluster. Close encounters of member stars may also increase the velocity of one of the members beyond the escape velocity. WebbIMO, There should be a Forward Velocity indicator, and a Total Velocity indicator, and then on the TVV Pip should be an additional (or the only) total velocity number for the player. There should also be a negative TVV. If you're travelling backwards, it different symbol with a negative number should indicate the direction you're moving away from. pampa tx time zone
