HST/STIS observations of sdBV stars: testing diffusion and pulsation theory
S. J. O'Toole, U. Heber, P. Chayer +3
We present the initial results of an abundance analysis of echelle UV spectra of 5 hot subdwarf B (sdB) stars. These stars have been identified as core helium burning objects on th…

MSST observations of the pulsating sdB star PG1605+072
S. J O'Toole, S. Falter, U. Heber +4
We present the first results from the MultiSite Spectroscopic Telescope (MSST) observations of the sdBV star PG1605+072. Pulsating sdB stars (also known as EC14026 stars) offer the…

Colour ratios of pulsation amplitudes in red giants
J. P. Huber, T. R. Bedding, S. J. O'Toole
We have analysed the three-colour photometry of 34 pulsating red giants that was published by Percy, Wilson and Henry (2001). As is common with semiregulars, many of these stars ha…
