    Cross-Correlation of Tenerife Data with Galactic Templates-Evidence for Spinning Dust?
    The recent discovery of dust-correlated diffuse microwave emission has prompted two rival explanations: free-free emission and spinning dust grains. We present...

    Crucial aspects of the initial mass function. I. The statistical correlation between the total mass of an ensemble of stars and its most massive star
    Context. Our understanding of stellar systems depends on the adopted interpretation of the initial mass function, IMF φ(m). Unfortunately, there is not a common...

    Crucial aspects of the initial mass function. II. The inference of total quantities from partial information on a cluster
    Context. In a probabilistic framework of the interpretation of the initial mass function (IMF), the IMF cannot be arbitrarily normalized to the total mass, ℳ...

    Cyclic brightening in the short-period WZ Sge-type cataclysmic variable SDSS J080434.20+510349.2
    Aims: We observed a new cataclysmic variable (CV) SDSS J080434.20+510349.2 to study the origin of long-term variability found in its light curve. Methods: Multi...
