Are the nearby and photometric stellar luminosity functions different ?
Abstract
The stellar luminosity function derived from the sample of stars within 5.220 pc is the nearby luminosity function. The luminosity function obtained from deep low spatial resolution surveys to distances of typically 100200 pc is the photometric luminosity function. We obtain and tabulate a best estimate of the parent distribution from which Malmquistcorrected photometric luminosity functions are sampled. This is presently the most accurate and precise available estimate of the true distribution of stars with absolute magnitude for M_{ν} < 16.5, as derived from lowresolution surveys. Using rigorous statistical analysis, we find that the hypothesis that the nearby and photometric luminosity functions estimate the same parent luminosity function can be discarded with 99% confidence or better for M_{ν} > 13, M_{bol} > 10.
