    A Massive AGB Star as Source of Short-Lived Nuclei in the Early Solar System
    The origin of short-lived radioactive nuclei at the time of the formation of the Sun is a much debated mystery in modern astronomy. We show that abundance...

    Asteroids as the parent bodies of meteorites: compositional
    Due to their orbits, near-Earth asteroids (NEAs) have been considered the most evident parent bodies of meteorites. Dynamical models show that NEAs come...

    Dependence of the population index on the radiant zenithal distance
    By integrating the differential equation system of the single-body meteor theory which describes meteor flight in the atmosphere, we show that the population...
