Record circular polarization discovered in the shortest period magnetic cataclysmic variable, RE 1307+535.
Abstract
We report the discovery of very strong, variable (+ 50 to -20 per cent) circular polarization in the ROSAT EUV source RE 1307+ 535 in the red (R band) spectral region. The amplitude and the peak value of the broad-band circular polarization are the largest observed so far in any astronomical object. Key words: polarization - stars: individual: RE 1307 + 535 - stars: magnetic fields - novae, cataclysmic variables - ultraviolet: stars.
