    Spectroscopy of Pre-CV Candidates in the Open Cluster M 67

    The systematic study of selected open clusters by our team has lead to the production of the best set of Strömgren photometry ever obtained of the old open cluster M 67. Its analysis has shown a previously unk...

    The Shape of the Blue/UV Continuum of B3-VLA Radio Quasars

    We present some results based on optical photometry of an unbiased subsample of 64 sources, from a sample of radio quasars 80 per cent complete. The quasars (z=0.4-2.8) show approximately a similar spectral en...
