Here's a Christmas present for Alex (Jarva)

Magnetic fields on O-Class stars (http://www.physorg.com/news/2010-12-magnetic-fields-o-class-stars.html)



They go on to say they've only just been able to detect non-thermal spectra (concluded its synchrotron radiation) from one of five sampled 'O' Class stars. The question remains as to where the relativistic electrons come from (needed to emit synchrotron radiation & its spectrum).

And why didn't they detect it from the other four in the sample.

Actually, its way too small a sample size to make much at all from this research, but this is partially due to the comparative rarity of "O" class stars and detection of synchrotron spectra for such distant stars.

Very interesting article, none-the-less.

Cheers
