67P/Churyumov-Gerasimenko April 5, 2016 Dust Tail Syndynes
Comet 67P/Churyumov-Gerasimenko Apr 5, 2015 with plotted dust tail syndynes
Measured tail point corresponds to syndyne with beta = 0.0009 and tau = 345 days
Finson-Probstein analysis of dust tail shows it is made up of large particles released approximately 345 days prior to the observation
with beta factor = 0.0009 or 9.0E-4
assuming solar radiation pressure efficiency coefficient = 1 and dust density = 1000 kg/m^3
dust particle radius (m): 6.3E-4 or about 630 microns
Generated syndyne for beta = 0.0009 gives position angle of 295.5 degrees for tail length of 11.8 arc minutes passes through measurement point.
Other syndynes fall above or below the observed and measured tail. Syndynes plotted include beta = 0.0003, 0.0005, 0.0009, and 0.0010
