The nascent wind of AGB star R Doradus: evidence for a recent episode of
  enhanced mass loss
  We analyse ALMA observations of the SO($J_K=6_5-5_4$) emission of the
circumstellar envelope of oxygen-rich AGB star R Dor, probing distances between
20 and 100 au from the star where the nascent wind is building up. We give
evidence for the slow wind to host, in addition to a previously observed
rotating disc, a radial outflow covering very large solid angles and displaying
strong inhomogeneity both in direction and radially: the former takes the form
of multiple cores and the latter displays a radial dependence suggesting an
episode of enhanced mass loss having occurred a century or so ago.
