Non‐linear behaviour of the pulsating white dwarf G29‐38 – II. Analysis of the phase spectrum

An analysis of the phase spectrum of the DA pulsating white dwarf G29–38 over many seasons has been performed. This complements a companion paper which analyses the evolution of the temporal spectrum of G29–38. We show that, with one exception, the rela ...

Non-linear behaviour of the pulsating white dwarf G29-38 - III. Relative amplitudes of the cross-frequencies

François Richard Vuille

In each season when the DA pulsating white dwarf G29–38 has been observed, its period spectrum appears very different, but it always contains a forest of harmonics and cross-frequencies. The ratio of the amplitude of these non-linear frequencies Ac to the ...

Initial and Final-State Effects in Photoemission from Gold Clusters

Giorgio Margaritondo

Size-dependent effects in the core-peak and Fermi-edge features of Au-cluster photoemission spectra have been investigated for two different substrates: polycrystalline and highly oriented pyrolytic graphite. In contrast with common substrates such as amor ...
