Such a heavy stellar population is unusual in the larger universe, where newly formed stars tend to show the same distribution of masses — called the initial mass function. (newscientist.com)
«The referee reports were pretty ugly,» he says, citing the widespread belief that the initial mass function is universal. (sciencemag.org)
It consists of the superposition of the planet and BD companion mass distributions, assuming that we can extrapolate the RV measured companion mass function for planets to larger separations and the stellar companion mass - ratio distribution over all separations into the BD mass regime. (arxiv.org)
