International audience; Six very successful Very Long Baseline Array (VLBA) calibrator survey campaigns were run between 1994 and 2007 to build up a large list of compact radio sources with positions precise enough for use as very long baseline inter

We investigate the paths of several probable members of the young association around the star TW Hydrae (TWA) with accurate distances, proper motions and radial velocities. We find that three of the previously identified members, TWA 1, TWA 4 and TWA

Observations of the centimeter radio emission of T Tau in 2003 June are consistent with the radio source T Tau N being coincident with the optical star (T Tau A) and its radio emission due predominately to a stellar wind. The absolute position of rad
