  The number of exoplanets found with periods as short as one day and less was
surprising given how fast these planets had been expected to migrate into the
star due to the tides raised on the star by planets at such close distances. It
has been seen as improbable that we would find planets in such a small final
fraction of their lives. The favored solution has been that the tidal
dissipation is much weaker than expected, which would mean that the final
infall would be a larger fraction of the planets' life. We find no reason to
exclude the explanation that a small number of planets are continuously sent
migrating inwards such that these planets indeed are in the last fraction of
their lives. Following the observation that the distribution of medium planets
disfavors tidal dissipation being significantly weaker than has been found from
observations of binary stars, we now show that the numbers of planets in such a
"flow" of excess planets migrating inwards is low enough that even depletion of
the three-day pileup is a plausible source. Then the shortest period occurrence
distribution would be shaped by planets continuously being sent into the star,
which may explain the depletion of the pileup in the Kepler field relative to
the solar neighborhood (Howard et al. 2012, hereafter H12). Because Kepler
observes above the galactic plane, H12 suggested the Kepler field may include
an older population of stars. The tidal dissipation strength in stars due to
giant planets may be not greatly weaker than it is in binary stars.
