“…Video rate CCD detectors have been used to study meteoroid impacts on the darkened lunar surface (Bellot Rubio et al 2000a,b, Ortiz et al 2002, Yanagisawa k Kisaichi 2002, Artemeva et al 2001. ; on mathematically inverting the observational data to infer meteor-fireball properties (Pecina, 2001; ReVelle & Ceplecha 2001a); on inferring shape change characteristics of meteor fireballs from an analysis of very precise bolide cases (ReVelle k Ceplecha 2001b); on hypersonic aerodynamic, equilibrium, chemically-reacting air temperature computations (Thames et al 2000); on transitional to free molecule flow effects (Popova et al 2001), on meteoroid explosions and on the general problems of meteor and bolide modeling (Kruchynenko, 2001); on Leonid entry modeling and its applications (ReVelle 2001a,b;Popova et al 2001); on quasi-continuous fragmentation processes (Kuznetsov & Novikov 2001); on a semi-empirical differential luminous efficiency parameter (ReVelle & Ceplecha 2001a); on aerodynamic forces affecting fragments dispersion following break-up (Su 2001); on meteoroid bulk density determinations (ReVelle 2001e). Artemieva & Shuvalov (2001) examined bolide fragmentation effects in general in a planetary atmosphere.…”
