    Ground-based observations of the β Cephei CoRoT main target HD 180 642: abundance analysis and mode identification
    The known β Cephei star HD 180 642 was observed by the CoRoT satellite in 2007. From the very high-precision light curve, its pulsation frequency spectrum could...

    Growth of galactic bulges by mergers. I. Dense satellites
    Andredakis et al. (cite{r3}) fit Sersic's law mu (r) ~ r1/n to the bulges of the Balcells & Peletier (cite{r5}) galaxy sample, and infer that n drops with...
