Meteoroids: Sources of Meteors on Earth and Beyond

Galina O. Ryabova is Principal Researcher at Tomsk State University, Russian Federation. Her research interests include the mathematical modelling of meteoroid streams and interrelations in the asteroid–comet–meteoroid complex. She has served on the Organizing Committee of the International Astronomical Union's Commission on 'Meteors, Meteorites and Interplanetary Dust', and is a council member of the International Meteor Organization (IMO).

David J. Asher is Visiting Research Fellow at Armagh Observatory and Planetarium, whose interests include solar system dynamics. His work with Robert H. McNaught brought the Leonid meteor storms of 1999–2002 to public attention worldwide. He has served on the Organizing Committee of the IAU's 'Meteors, Meteorites and Interplanetary Dust' Commission and, through his long involvement with the IMO, maintains extensive links with the active amateur meteor community in many countries.

Margaret D. Campbell-Brown is Associate Professor at the University of Western Ontario and Vice-President of the IAU's Commission on 'Meteors, Meteorites and Interplanetary Dust'. Her research focuses on the origin of sporadic meteoroids and their physical and chemical properties, and her telescopic tracking system for meteors has produced unprecedented data on the fragmentation and dynamics of small meteoroids.
