Abstract

Analysis of middle-resolution optical spectra of comet C/2000 WM1 (LINEAR) obtained on November 22 and 24, 2001 and on Apr. 5, 2002 with the 2.12-m reflector of the Guillermo Haro Astrophysical Observatory is given. Analysing distribution of brightness along the spectrograph slit in emission lines C2, C3, CN on Nov. 22, 2001 we determined some physical parameters of these neutral molecules the velocity of expansion of molecules from the nucleus and their life time. Using Haser’s model the rates of gas-productivity in emission lines of C2, C3, CN molecules for Apr. 5, 2002 were determined.
