Meteoroid Distribution, Origin
Scientific paper
We have modelled the sporadic meteoroid distribution assuming (I) long and short-period comets to be the sole sources of particles and (II) the Poynting-Robertson effect to be the only depletion mechanism. We find the steady-state distribution of the orbits of meteoroids released from these sources and calculated the radiant and velocity distributions of these particles as they would be observed by an Earth-based meteor radar. The method predicts the Helion/Antihelion and the Apex sources and also provides an explanation for the North and South Toroidal sources. Agreement of the theoretical predictions and the observations obtained from the Harvard Radio Meteor Project is excellent.
