    Properties of starspots on CoRoT-2
    Context. As a planet eclipses its parent star, a dark spot on the surface of the star may be occulted, causing a detectable variation in the light curve. Aims...

    Properties of sunspot light bridges on a geometric height scale
    Context. Investigating light bridges (LBs) helps us comprehend key aspects of sunspots. However, few studies have analyzed the properties of LBs in terms of the...

    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...
