Abstract

Following a previous paper (Tanaka et al., 1990, Publ. Natl. Astron. Obs. Japan, 1), near-infrared spectroscopic observations of cool carbon stars have been continued with the Fourier transform spectrometer and the 188 cm reflector at Okayama Astrophysical Observatory. Sixty-six spectra of 63 carbon stars were analyzed. Eighteen stars were newly added to our program stars, and the total number of the analyzed carbon star reached 101
