Abstract
We report on the preliminary analysis of the high-resolution spectrum of Comet C/2000 WM1 (LINEAR), obtained on Dec. 1, 2001 with the Fiber fed Extended Range Optical Spectrograph (FEROS) installed on the 1.52-m telescope of ESO (Chile). Many emission lines of the molecules C2, C3, CN, CH, CH+, NH2, CO, CO+, H2O+ and, presumably, C2 − were identified in the spectral range 400–900 nm.
Also, near-infrared photometry was performed on Dec. 2 and 3, with the infrared camera (CamIV) attached to the 0.60-m Boller and Chivens telescope of the Pico dos Dias Observatory (LNA/MCT), Brazil. We report the preliminary and comparative analysis of the I—J and J—H color indices.
