1. Armagh Observatory Preprint No. 306
... We present an analysis of an optical blue spectrum of the pulsating helium star V652 Her (=BD+13 3224$) in order to determine its effective temperature, surface gravity and chemical composition. ... The surface composition is characterised by abundances of nH=0.009, He=0.988, nC~0.000040, nN=0.0025 and nO=0.00010 (number fractions). ... If V652 Her was formed by the merger of two white dwarfs, its surface composition demands that they should both be helium white dwarfs. ...
