According to the discovery team , this is best explained by assuming they were absorbed by solid material in the form of an equatorial disk having denser rings or arcs , with particles perhaps many decimeters to about a meter in diameter . According to the discovery team , the pattern of depletion is best explained by assuming the electrons are absorbed by solid material in the form of an equatorial disk , which contains within it several denser rings or arcs , of particles perhaps several decimeters to approximately a meter in diameter .
