Show other versions (1)

The present paper is of three folds. First, to provide some basic descriptive statistics parameters for the apparent and absolute magnitudes of the nearby stars of spectral type F8V stars. Second, to establish the frequency functions and of the absolute and apparent magnitudes for these stars. T...
