Descripción
The B fields in OB stars (BOB) survey is an ESO Large Programme
collecting spectropolarimetric observations for a large number of
early-type stars in order to study the occurrence rate, properties, and
ultimately the origin of magnetic fields in massive stars. A total of 98
objects was observed over 20 nights with FORS2 and HARPSpol to July
2014. Preliminary results indicate that the fraction of magnetic OB
stars with an organised, detectable field is low. This conclusion, now
independently reached by two different surveys, has profound
implications for any theoretical model attempting to explain the field
formation in these stars. We also discuss some important issues
addressed by our observations (e.g., the lower bound of the field
strength) and the discovery of some remarkable objects.

Massive stars has been many times claimed as Cosmic Engines and Gifts of Nature for the study of the Universe, from the Solar neighbourhood to the large-z Universe. The complete understanding of the physical properties and evolution of massive stars (and their interplay with the ISM) is crucial for many fields of Astrophysics and, ultimately, to
