Abstract
A star in the Milky Way’s disk can now be at a Galactocentric radius quite distant from its birth radius for two reasons:
either its orbit has become eccentric through radial heating, which increases its radial action JR (“blurring”), or merely its
angular momentum Lz has changed and thereby its guiding radius (“churning”)
