We carried out optical low-dispersion spectroscopic observations of the brightest fragments "B” and "C” of comet 73P/Schwasmann-Wachmann 3 (hereafter SW3) by the 2-m "NAYUTA” telescope with the optical spectrograph MALLS at NHAO (Nishi-Harima Astronomical Observatory) in Japan.
Comet SW3 is known as a split comet, and its fragments are the best targets to investigate homogeneity of the cometary nucleus. We observed fragments "B” and "C” in 2006 early and middle of May, in the vicinity of the closest approach to the Earth on 2006 May 12, UT. Comet SW3 approached less than 0.07AU from the Earth provided us high spatial resolution data of its coma.
We report the gas production rate ratios of CN, C2, and NH2 relative to H2O and the gas-to-dust ratios of fragments "B” and "C". Both fragments are significantly depleted in C2 compared with other comets, and these fragments are similar to each other in chemical composition. This result suggests that the nucleus of the parent body of comet SW3 was homogeneous in chemistry.
