View Full Version : Tau Scorpii's Magnetic Fields Blaze X-Rays

SUMMARY: Our Sun can send out its share of solar flares and coronal mass ejections, but compared to other stars, it's relatively calm. One example is tau Scorpii, 5-6 times larger than the Sun and visible with the unaided eye. Astronomers have discovered that it has a complex network of magnetic field lines which channel its solar winds into thin arcs. The high points of these arcs blaze brightly in the x-ray spectrum.

Is the incredible magnetic field slowing the rotation, or is the incredible magnetic field the result of a slower rotational velocity?

Edit: There's an error in the story. 30,000 km/sec is not one percent the speed of light, it's ten percent the speed of light. 300,000,000 m/sec or 300,000 km/sec is c. Hence 30,000 km/sec is c/10....it also happens to be the maximum velocity for type 2 supernovae ejecta clouds (Fillipenko, Alexei, Ap. J..re: SN1987a). Pete.:shifty:

WOW!!! and still no mention of the incredible electrical forces involved :(
