Study of coefficients of phase in light curves cometarys

In this work have been investigated and analyzed a total of 17 visual light curves of comets , was calculated with the average coefficient of phase for 17 differents comets , the first report of this type Meech and Jewitt ( 1987 ) obtaining coef. fase = 0.018 mag / deg , the author of this work has had difficulty in calculating this value due to the rotational amplitude of comets usually about 1.1 magnitudes (Belton 1986), this study has found a value of 0.040 mag / deg .

My next job of investigation this based in the work " HCN PRODUCTION FROM COMET HALLEY " of F.Peter Schloerb and co-authors published in The Astrophysical Journal 310 , L55-L60 , 1-November 1986 , the correlation visual magnitudes - HCN production rates , the equation : log Q ( HCN ) = 27.57 - 0.24 ( m1 - 5 log (delta)) is applied for various periodics comets in the work of J.P.Navarro Pina , more information in next publications this blog .
