HCN PRODUCTION RATE OF COMET C/2011 L4 PANSTARRS

HCN PRODUCTION RATE IN PANSTARRS COMET C/2011 L4 calculated the HCN's production rate of comet C/2011 L4 PANSTARRS based in 107 reduced's magnitudes from database : ICQ , Comet Obs , observadorescometas and Cometas LIADA , the preliminary results from the heliocentric distance range 2.5 < r < 5.5 show the HCN equation : log Q [ H2O ] = 25.35 + ( -0.0003 ) * R coefficient correlation R = -0.98 The outflow velocity in R = 5.189 is 1.85 km s-1 , based in v(HCN) = 1.59 * r ( -1/2 ) and R = 2.778 is 0.99 km s-1 The HCN production for PANSTARRS comet is based in work '' Observations of HCN in comet Halley ''by F.P.Schloerb et at 1987, published in Astronomy and Astrophysics 187 , in equation log Q [ HCN ] = 27.58 - 0.24 ( m1-5log(d))
