Abstract
The OH 1612 MHz maser emission from four objects which are probably in transition between the AGB and the PN stage has been mapped with MERLIN. The basic parameters of their circumstellar envelopes are determined. There are indications of episodic variations in mass loss rates in two objects. The structure of linearly polarized emission is well resolved in two envelopes indicating highly ordered circumstellar magnetic fields.
