We have made a molecular line survey of the carbon star IRAS 15194-5115 in the 3 and 1.3
mm bands with the 15 m SEST (Swedish-ESO Submillimetre Telescope). Molecular
abundances are derived and compared with those of IRC+ 10216. C2H, C4H, C3H2, and
SiO are more abundant in IRAS 15194-5115 by about a factor of three, while the
abundances of CN, CS, SiS, HNC, SiC2, C3H, C3N, and HC3N are similar in the two
sources. The C-13 species are more abundant in IRAS 15194-5115, and we derive a C …
