In the preprint of "The HARPS search ... XXXI. The M-dwarf sample" by
Bonfils et al,
[
http://arxiv.org/abs/1111.5019 ] ,
Figure 1 and comments in section 8 clearly indicate an anomalously low
abundance of planets for M-dwarfs with masses below 0.25 solar mass.
The authors state: 的t is striking that all planet-host stars are
found in the brightest and more massive halves of the two [M-dwarf]
distributions.
I actually predicted this phenomenon in 2001, and updated my paper
with initial supporting data in 2008.

Discrete Scale Relativity definitively predicted that there would be
an abnormally low abundance of planets for M-dwarfs with masses below
0.25 solar mass. If DSR is correct, then the anomaly is not primarily
due to any selection effect, but is an actual physical phenomenon with
a definite physical explanation.
Discrete Scale Relativity might seem a bit unorthodox at first
reading, but it has already successfully predicted pulsar-planet
systems before they were discovered in the 1990s, and predicted
trillions of unbound planetary-mass "nomad" objects over two decades
before their discovery [Sumi et al, Nature, 2011].
