Revised Abundances & Ionizing Fluxes for [WC]-Type PN Central Stars Using Line Blanketed Models
Published online by Cambridge University Press: 26 May 2016
Abstract
UV (IUE), far-UV (FUSE) and optical (INT) spectroscopy of four Galactic [WC]-type PN central stars are analysed by means of sophisticated model atmosphere codes which allow for detailed line blanketing and clumping, and make comparisons with earlier non-LTE models. Crucially, we find no systematic difference between carbon abundances amongst late and early-type [WC] stars, removing the main obstacle against evolution from [WCL] to [WCE] subtypes.
