    COYOTES III: observational evidence for a lower limit to the rotational velocity of ZAMS G and K dwarfs.
    In order to provide additional constraints to current models of angular momentum evolution of solar-type stars, we have conducted a period-determination program...

    COYOTES IV: the rotational periods of low-mass Post-T Tauri stars in Taurus.
    We monitored the light variations of 58 weak-line T Tauri stars in Taurus, recently discovered in the X-ray wavelength range during the ROSAT All-Sky Survey. We...

    Coyotes-I - the Photometric Variability and Rotational Evolution of T-Tauri Stars
    In a multi-site photometric campaign to monitor T Tauri stars (TTS) in the Taurus-Auriga cloud over more than two months - dubbed Coordinated Observations of...

    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...

    Cu and Zn in the early Galaxy
    We present Cu and Zn abundances for 38 FGK stars, mostly dwarfs, spanning a metallicity range between solar and [Fe/H] = -3. The abundances were obtained using...

    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...

    Damped transverse oscillations of interacting coronal loops
    Damped transverse oscillations of magnetic loops are routinely observed in the solar corona. This phenomenon is interpreted as standing kink magnetohydrodynamic...

    Damping of prominence longitudinal oscillations due to mass accretion
    We study the damping of longitudinal oscillations of a prominence thread caused by the mass accretion. We suggested a simple model describing this phenomenon...
