https://doi.org/10.1007/978-3-8350-9049-1It has been found that the close spectroscopic pair of this system consists of a G type primary and a late type secondary, which most likely is a T Tauri star. As such, the system is semidetached and a mass transfer takes place between the components.

Sektorenspezifische Regelungen im IWR,By a comparison of Trapezium-type multiple star systems in the Abastumani Catalogue and the famous Catalogue of Stellar Associations and Clusters, it is confirmed that the great number of Trapezium-type multiple stars, which belong mostly to spectral classes O-B2, are found in associations and clusters.

Photometric Investigation of Visual Binaries with a Component above the Main SequenceVisual binaries containing a component above the main sequence in combination with a main-sequence star provide an excellent opportunity for determining absolute magnitudes of evolved stars. Some aspects of this technique are discussed, and preliminary results are presented.

Internationales Steuerrecht in der Praxisossible to fit a convective core into the point source model of stellar structure integrated by Cowling three years earlier. The free parameter in the fitting process could be fixed with the thermonuclear reaction rates, the first realistic stellar model for a massive main sequence star was construc
