... Programme . ... Abstract: The five-year WMAP results coupled with single-dish observations at low frequencies have provided us with the first broad-band, spatially resolved observational constraints on the radio spectral properties of the giant lobes of Centaurus A. I will review what this tells us about the dynamics and activity history of the source and comment on the implications for inverse-Compton emission and high-energy particle acceleration in the giant lobes. go back . ...

Next: V652HER AND MERGED BINARY Up: EXTREME HELIUM STARS: PULSATION Previous: MASSES . Although pulsations in EHes appear to be ubiquitous, it is not possible to summarize their properties with a single definition. ... The first discovery of pulsation in an EHe was made by Landolt (1975), who discovered a 0.1day photometric period in V652Her, and by Hill et al. (1981), who measured the radial velocity curve and demonstrated the variations were due to radial pulsation. ... 1987, Jeffery et al. ...
