Scientific paper

Stellar mass distribution is discussed with attention given to the cumulative number of stars which have masses greater than M solar masses. 74% (by mass) of the stellar population within 10 pc of the sun is found to obey a given Weibull distribution. The fit to the Weibull distribution supports the supposition that the stars in the vicinity of the sun have been produced by a fragmentation and condensation process which encompassed a strong tendency to remove all masses less than 0.05 solar masses. The median mass of the distribution (the mass percentage being equal to 50%) is 0.474 solar masses.
