Scientific paper

Ascending branches of theoretical light curves corresponding to three models are compared for 29 observed meteors. In 'Model A' meteor luminous efficiency (beta) is a linear function of meteoroid velocity; in 'Model rho-I' beta is a function of both meteoroid velocity and the product of atmospheric density and meteor light flux; in 'Model-rho-v' beta is a linear function of the product of atmospheric density and meteoroid velocity. Analysis of discrepancies among the observational data and theoretical light curves shows that 'Model-rho-I' may be successfully applied in meteoritic studies. The photometric masses of meteors are found to be less reliable than the masses estimated by using relationships associating the parameters of meteor emission at maximum light with initial mass.
