Abstract
The original title of this contribution was "Magnetic Fields in the
Vicinity of Young Stars". One of the goals was to show the impact of
the large scale magnetic field on the gravitational collapse leading
to star formation, and also to discuss some of Jean-Louis Leroy's
contributions to the measurement of the polarisation, hence the
direction of the magnetic in the interstellar medium made with
STERENN, the polarimeter he and Jean-François Leborgne built for the
Pic-du-Midi observatory. Another goal of the talk was to survey the
state of our knowledge of the magnetic field in the immediate
circumstellar environment of young stars. In doing that we discovered
an interesting correlation. Therefore, this paper presents only a
brief overview of the original talk presented at the
conference. Instead, it emphasizes largely on what we consider to be
the most interesting aspect of what was presented, namely, the
alignement of YSO, and in particular T Tauri stars, with the local
magnetic field in Taurus.
