Abstract

The Australia Telescope Compact Array (ATCA) has been used to make 4.8-GHz observations of 24 fields containing post-main-sequence stars. These stars were selected from a sample of late-type (spectral types G, K and M) giants and bright giants within 30 pc claimed by Slee et al. (1989, MNRAS, 239), from observations with the Parkes radio telescope, to be variable non-thermal radio emitters. No significant 4.8 GHz radio emission was detected from these stars. Non-detection of any stars with the ATCA is an improbable result (given the claimed Parkes detection rates and the superior sensitivity of the ATCA) and calls for a re-analysis of the original Parkes 8.4-GHz observations
