An Apparent Gap in Stellar Mass Distributions around 0.7 Solar Masses and a Possible Explanation

Mass functions for samples of white dwarf stars and for a large heterogeneous sample of nearby stars appear to have unexplained deficits in the range of 0.70 to 0.75 Solar Masses. The existence, or non-existence, of this anomaly constitutes a definitive test of a fractal cosmological model that inherently predicts a gap in stellar mass functions at about 0.73 Solar Masses.
