Confrontation between Quantized Periods of Some Extra Solar Planetary Systems and Observations
... The quantization numbers mentioned by [2,3], have been used in the relation (13), to find the periods of the solar system planets. The obtained values are tabulated in Table 1. In the same table a comparison between the ...

Liberating exomoons in white dwarf planetary systems
... It is clear that the unbinding of exomoons from their parent plan- ets will initiate a phase of dynamical evolution which is likely to be strongly chaotic. The unbound exomoons will initially occupy orbits which cross ...
