Detailed morphology of RWT 152 characterized

Physical conditions and chemical abundances determined

Insights into the nature of sdO central stars in planetary nebulae

Abstract

RWT 152 is one of the few planetary nebula with an sdO central star. We present subarcsecond red tunable filter imaging and intermediate-resolution, long-slit spectroscopy of RWT 152, obtained with OSIRIS/GTC, which allow us to describe in detail its morphology and to obtain its physical conditions and chemical abundances.
