Star formation history, double degenerates and type Ia supernovae in the thin disc
stars: white dwarfs − stars: evolution − stars: binaries: close − supernovae: general − Galaxy: evolution − Galaxy: structure

We investigate the relation between the star formation history and the evolution of the double-degenerate (DD) population in the thin disc of the Galaxy, which we assume to have formed 10 Gyr before t...

A research that we conducted in 1963 on the evolution of
the binaries based on the available orbital data to obtain a philosophical
degree, led to the establishment of an interesting and new diagram...

An integrated distribution function is derived for visual double
stars according to the magnitude difference Δm between the components. For this
purpose the author uses a sample of 1626 double stars...
