Mass-loss and diffusion in subdwarf B stars and hot white dwarfs: do weak winds exist?

Context. According to previous investigations, the effect of diffusion in the stellar atmospheres and envelopes of hot white dwarfs and subdwarf B (sdB) stars strongly depends on the presence of weak winds with mass-loss rates $\dot M$ < 10-11 $M_{\odot}/\rm yr$. Aims. As in most of these stars w...
