Interstellar 12C/13C ratios toward six stars

Creators

Description

Carbon isotope ratios a = N(12C)/N(13C) are measured for interstellar CH+ molecules toward six stars, using the X4232 line. Negative results of high sensitivity are obtained for the 13CH+ line in all cases, yielding lower limits ranging from a> 20 to a> 77.
