    Spectral evolution of the He-Poor supernovae 1990U in NGC 7479 and 1991A in IC 2973
    We present the spectral evolution, from about one to six months after optical maximum, of two type Ic supernovae, 1990U in NGC 7479 and 1991A in IC 2973 (UGC...

    The age decay of stellar magnetic activity in MS field solar-type stars
    The age decay of two indicators of the stellar magnetic activity (λ2800 Mg II emission flux and λ10830 He I equivalent width) have been studied for field solar...

    The Carbon Star DY Persei May Be a Cool R Coronae Borealis Variable
    Optical and near-IR photometry suggests that the carbon star DY Persei exhibits fadings similar to those of R Coronae Borealis (RCB) variables. Photometric...
