    On a New Near-Infrared Method to Estimate the Absolute Ages of Star Clusters: NGC 3201 as a First Test Case
    We present a new method to estimate the absolute ages of stellar systems. This method is based on the difference in magnitude between the main-sequence turnoff...

    On a New Parameter to Estimate the Helium Content in Old Stellar Systems
    We introduce a new parameter Δξ-the difference in magnitude between the red giant branch (RGB) bump and the point on the main sequence (MS) at the same color as...

    On emission-line spectra obtained from evolutionary synthesis models. II. Scale-relations and the estimation of mass dependences
    Aims: In this paper we study the influence of the ionizing cluster mass on the emission line spectrum of H ii regions in order to determine the influence of low...

    On the Absolute Age of the Globular Cluster M92
    We present precise and deep optical photometry of the globular M92. Data were collected in three different photometric systems: Sloan Digital Sky Survey (g ', r...

    On the Absolute Age of the Metal-rich Globular M71 (NGC 6838). I. Optical Photometry
    We investigated the absolute age of the Galactic globular cluster M71 (NGC 6838) using optical ground-based images (u\prime ,g\prime ,r\prime ,i\prime ,z\prime...

    On the action of UV photons on hydrogenated fulleranes C60H36 and C60D36
    Fulleranes, the hydrogenated fullerenes C60H36 and C60D36 have been synthesized in n-hexane where they show an absorption maximum at 217 nm in their electronic...

    On the alumina dust production in the winds of O-rich asymptotic giant branch stars
    The O-rich asymptotic giant branch (AGB) stars experience strong mass-loss with efficient dust condensation and they are major sources of dust in the...

    On the anticorrelation between pericentric distance and inner dark matter density of Milky Way's dwarf spheroidal galaxies
    An anticorrelation between the central density of the dark matter (DM) halo (ρ 150, DM) and the pericentric distances (r p) of the Milky Way's (MW's) dwarf...

    On the C60 Fullerene Adduct with Pentacene: Synthesis and Stability
    C60 fullerene and pentacene were reacted under mild conditions in toluene, yielding the monoadduct, which was characterized by electronic absorption and Fourier...
