摘要：

We describe the high resolution spectrum of the Population II symbiotic system AG Dra during quiescence, and the line profile of the H and He emission and their time variation. We analyze the multicolor photometric variability during the last active phase and discuss the peculiar time behavior of the supersoft X-ray source associated with AG Dra.
