Water-Trapped Worlds Possible Around Red Dwarf Stars?
An artist's concept of a rocky world orbiting a red dwarf star. . A recent paper submitted by Associate Professor of Astronomy at Columbia University Kristen Menou to the Astrophysical Journal suggests that tidally-locked planets in close orbits to M-class red dwarf stars may host a very unique hydrological cycle.

The real gem here is the log distance plot coupled with the size of the astronomical body.
The solar system on this plot will line up the planets like a string of pearls (with Ceres in the Jupiter-Mars asteroid belt gap).
The Gleise exoplanet results indicate some drift from the string of pearls plot implying a bit of tidal forcing of the objects in orbit with the outermost drifting out & the innermost drifting in with time. A similar result occurs in the Saturn system with Titan drifting outward & the inner satellites drifting inward with time.
This log distance plot indicates that the Gleise exoplanet system is relatively old.
