Abstract: Mass loss rates are predicted as a function of surface gravity for a stellar mass M = 0.6M, effective temperatures Teff = 50000K and 60000K and metallicities between solar and Z/Z = 0.01. In addition, it is checked in which cases the one component description of radiation driven winds may be justified. For central stars of planetary nebulae with log g ≤ 4.7 the results predict mass loss rates in the range 10−10M/yr ≤ dM/dt ≤ 10−7M/yr where the dependence of dM/dt on the metallicity increases to larger gravities. For hydrogen-rich white dwarfs with log g ≥ 7.0 and solar or subsolar metallicity no steady outflow of all elements can exist.
