    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...
