Abstract
Abstract The wind of an asymptotic giant branch star is sufficiently strong that if it is slightly asymmetric, it can propel the star outside the open cluster of its birth or significantly alter its trajectory through a globular cluster. Therefore, if these stellar winds are asymmetric, one would expect a deficit of white dwarfs of all ages in open clusters and for young white dwarfs to be less radially concentrated than either their progenitors or older white dwarfs in globular clusters. This latter effect has recently been observed. Hence detailed studies of the radial distribution of young white dwarfs in globular clusters could provide a unique probe of mass loss on the asymptotic giant branch and during the formation of planetary nebulae both as a function of metallicity and for a limited range of stellar mass.
