Abstract

We present ten new radio continuum (RC) detections at catalogued planetary nebula (PN) positions in the Small Magellanic Cloud (SMC): SMPS6, LIN 41, LIN 142, SMPS13, SMPS14, SMPS16, J 18, SMPS18, SMPS19 and SMPS22. Additionally, six SMC radio PNe previously detected, LIN 45, SMPS11, SMPS17, LIN 321, LIN 339 and SMPS24 are also investigated (re-observed) here making up a population of 16 radio detections of catalogued PNe in the SMC. These 16 radio detections represent ∼15 % of the total catalogued PN population in the SMC. We show that six of these objects have characteristics that suggest that they are PN mimics: LIN 41, LIN 45, SMPS11, LIN 142, LIN 321 and LIN 339. We also present our results for the surface brightness—PN radius relation (_ −D) of the SMC radio PN population. These are consistent with previous SMC and LMC PN measurements of the (_ −D) relation.
