Critical Test of the Self-Similar Cosmological Paradigm: Anomalously Few Planets Orbiting Low-Mass Red Dwarf Stars

The incidence of planetary systems orbiting red dwarf stars with masses less than 0.4 solar masses provides a crucial observational test for the Self-Similar Cosmological paradigm. The discrete self-similarity of the paradigm mandates the prediction of anomalously few planetary systems associated with these lowest mass red dwarf stars, in contrast to conventional astrophysical assumptions. Ongoing observational programs are rapidly collecting the data necessary for testing this prediction and preliminary results are highly encouraging. A definitive verdict on the prediction should be available in the near future.

Planetary-Mass Dark Matter?

Sahu et al. recently reported tentative evidence for a large population of "free-floating" planetary-mass objects in a nearby globular cluster. If verified, this discovery is consistent with a prediction that the galactic dark matter has a substantial planetary-mass component.

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.

A Review of Mass Estimates for Galactic Dark Matter Objects

Empirical mass estimates for galactic dark matter objects, published between December 1991 and May 1999, are presented in tabular and graphical forms. Trends in the data are identified and uncertainties are discussed. Similarities among various stellar and dark matter mass functions are noted, and a possible identification of the galactic dark matter objects is suggested.

The Galactic Dark Matter: Predictions and Obsevations

After two decades of efforts to identify the enigmatic dark matter that comprises the dominant form of matter in our galaxy, the mass range for viable candidates appears to have been reduced by more than 50 orders of magnitude. Positive results have thus far been confined to the range: 10-7 Mo to 1.0 Mo, with apparent clustering within the ranges 10-5 Mo to 10-3 Mo and 0.08 Mo to 0.5 Mo. Positive and negative results are compared with specific predictions of cosmological models.
