Abstract :

[en] In recent years, the stars of the Of?p category have revealed a wealth of peculiar phenomena: varying line profiles, photometric changes, and X-ray over-luminosity are only a few of their characteristics. Here we review their physical properties to facilitate comparisons among the Galactic members of this class. As one of them his been proposed to resemble the magnetic oblique rotator theta(1) Ori C, though with a longer period, this latter object is also included in our study to illuminate its similarities and differences with the Of?p category.
