SYNCHRONE ANALYSIS AND SYNDYNE OF COMET C/2011 L4 PANSTARRS
Preliminar's analysis of the original image of Michael Jaeger ( Austria ) , and processed by J.P.Navarro Pina ( Spain ), by software astroart 5.0 , were applied to analyse the morphology of comet PANSTARR'S dust tail and the evolution of its streamers : 1- direct modelling of the brightness distribution in the tail 2- determination of streamers densities 3- synchrone analysis 4- syndyne analysis The time variable variable particle production rate is given by : N (t , B ) = N0 * B(p) * r (q,c ) * t N0 is an arbitrary scaling factor related to the total dust production q and p , free parameters . B = F rad / F grav denotes the ratio of the solar radiation pressure force vector , F rad , and the vector of the force gravitation F grav .B is dependent only on the bulk properties of the dust grains and can be related to a representative particle radius .
My second analysis of the light curve of comet C / 2021 A1 LEONARD, indicates in T-300, a stagnation in the rate of increase in brightness ...
