    On the variable spectrum of HD 45677 (FS Canis Majoris)
    { We have studied high-resolution optical spectra of the peculiar B[e] star HD 45677 (FS CMa) observed during 3 nights in October 1995. The main results of our...

    On the Variation of the Peak Asymmetry of Low-l Solar p Modes
    The resonant peaks of solar p modes show small amounts of asymmetry in frequency. Here, we use five independent sets of contemporaneous data, collected over a ~...

    On the Way to Graphene: The Bottom-Up Approach to Very Large PAHs Using the Scholl Reaction
    The Scholl reaction was adopted to synthesize the very large polycyclic aromatic hydrocarbons (VLPAHs) hexabenzocoronene (HBC), quaterrylene and dicoronylene as...

    On the Weakness of Diffuse Galactic Light off the Milky Way
    Observations have been selected in Tenerife Zodiacal Light Data, which make it possible to separate the diffuse galactic light from other components. Far from...

    On the White Dwarf Cooling Sequence of the Globular Cluster ω Centauri
    We present deep and precise photometry (F435W, F625W, F658N) of ω Cen collected with the Advanced Camera for Surveys (ACS) on board the Hubble Space Telescope...

    On the width distribution of penumbral filaments in sunspots
    The width distribution of the penumbral filaments is estimated using white light photographs obtained with a vacuum, Newtonian type telescope. Observations were...

    On the widths of emission lines in spectra of WC9 stars of different kinds
    Emission lines in the spectra of WC9 stars have been studied. It is shown that there are clear differences between the spectra of BD + 30 3639 and the central...

    On the wind momentum problem of O-type stars in the galaxy
    We have examined the wind momentum problem of O-type stars in the Galaxy. It is shown that the discrepancy between theoretical and empirical mass loss rates and...
