- The Tully-Fischer method relies on being able to relate the mass of a galaxy to its rotation velocity. Stars in the outer-most regions of the Milky Way galaxy, located at a distance of 50 kpc from the galactic centre, are observed to orbit at a speed vrot determine the mass in the Milky Way that lies interior to 50 kpc. Express your answer in units of the Solar mass. 250 km s-1. Using Kepler's 3rd Law,What is the mass of a star with a main-sequence lifetime of 6 billion years?Match each statement with the appropriate item (if the first corresponds to B and the next 4 to C, enter BCCCC) 1) group of stars that was formed all at the same time, with the same composition 2) the top of the main sequence of a cluster; more massive stars in the cluster have already evolved 3) globular clusters stars that are burning helium in their core 4) young, spread out star cluster 5) old, dense star cluster A. main sequence turnoff B. open cluster C. star cluster D. horizontal branch stars E. globular cluster
