GTC/OSIRIS observations of RWT 152, a case study of a planetary nebula with an sdO central star
arXiv:1512.08933 · doi:10.1051/eas/1571071
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.
