Description
The baryonic Tully-Fisher relation is a correlation between the quantity of stars and gas in a galaxy and its flat rotation speed. The relation found in external galaxies appears to hold for rotationally supported Local Group galaxies. It may also hold for some if not all of the pressure supported dwarfs. The flat rotation speed depends on dynamical mass, providing a constraint on total mass that is independent of other considerations.
