The chemical composition of Sakurai's Object.
KIPPER T. and KLOCHKOVA V.G.
Abstract (from CDS):
The atmospheric parameters and elemental abundances have been derived for Sakurai's object. The atmosphere of the star was found to be H deficient with enhanced carbon and s-process abundances. The effective temperature is Teff=7250K, logarithmic gravity, logg=1.0, and the microturbulent velocity, ξt=7±1km/s. These abundances and atmospheric parameters are close to the majority of cool R CrB stars. The chemical composition, fast brightening from the preoutburst state and the presence of PN indicates that Sakurai's object is a final helium flash object.
