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 .
