    Properties of the P Cygni wind found using the Self Absorption Curve method
    We have used the optical lines of N II and Fe III to study the wind of the luminous blue variable P Cyg. This was performed by applying a version of the Self...

    Prospects for high-z cluster detections with Planck, based on a follow-up of 28 candidates using MegaCam at CFHT
    The Planck catalogue of SZ sources limits itself to a significance threshold of 4.5 to ensure a low contamination rate by false cluster candidates. This means...

    Prospects of Stellar Variability Using a CCD - the Discovery of a New W-Ursae System in the Open Cluster NGC6802
    A search for stellar variability based on time resolved CCD observations for the open cluster NGC 6802, was conducted in June 1990 at the 2.5 Isaac Newton...

    PSR J0210+5845: Ultra-wide binary pulsar with a B6 V main sequence star companion
    We report on radio timing observations of PSR J0210+5845 that reveal large deviations from typical pulsar spin-down behaviour. We interpret these deviations as...

    Pulsating hot O subdwarfs in ω Centauri: mapping a unique instability strip on the extreme horizontal branch
    We present the results of an extensive survey for rapid pulsators among Extreme Horizontal Branch (EHB) stars in ω Cen. The observations performed consist of...

    Pulsation, binarity and close frequency spacing in $delta Scuti ta$ Scuti stars: BQ and BW Cancri. Results of the STEPHI VI campaign in Praesepe Cluster
    New pulsation modes in two delta Scuti stars of Praesepe cluster, BQ and BW Cnc, have been detected during the STEPHI VI campaign in 1995. In particular, 3...
