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.18 pages with 4 figuresAstrophysicsAn Apparent Gap in Stellar Mass Distributions around 0.7 Solar Masses and a Possible Explanationtext
