Interstellar dust and magnetic field at the boundaries of the Local Bubble. Analysis of polarimetric data in the light of Hipparcos parallaxes.

LEROY J.L.

Abstract (from CDS):

Hipparcos stellar parallaxes have been used to reanalyse existing interstellar polarization data. The main results are: (o) The nearest interstellar dust patches are at about 70pc in some directions, in others beyond 150pc. Thus the region devoid of dust, commonly identified with the Local Hot Bubble, is irregular in shape. (o) The interstellar magnetic field revealed by the nearest polarized stars is certainly not a smooth, uniform field along the Galactic equator. The structure seen is more complex and can no longer be dismissed as an artefact due to inaccurate stellar distances.
