A Preliminary Analysis of the Pulsating Extreme Helium Star V652 Her (Bd+13°3224)A preliminary fine analysis of the atmosphere of the pulsating extreme star V652 Her (=BD+13°3224) is reported. The mean effective temperature and temperature variation have been determined from the ionisation equilibria of Si and N. Both of these elements are strongly overabundant, whilst C appears to be underabundant.

Polarimetric Observations of Hydrogen Deficient StarsPolarimetric observations of HD 30353,SU Tau,XX Cam, R Cr B,UV Cas, BD+13° 3224,BD+10° 2179 and HD 124448 are presented. The linear polarization of HD 30353 is found to vary appreciably at Hα over a time scale as short as one day. It is also found that SU Tau shows significant variation in polarisation even at light maximum.

Introductory Commentsy unable to attend. This I am happy to do: the hydrogen-deficient stars are dear to my heart and even though I haven’t contributed anything to the subject for several years, it is certainly nice to be remembered. From an outsider, then, a few thoughts.
