Speeding past planets? Asteroids radiatively propelled by giant branch Yarkovsky effects
... Our model ignores the effect of collisions, which can play a vital role in shaping the debris fields of giant branch planetary systems (Bonsor & Wyatt 2010). These collisions can both modify the size distribution of ...

Resonant Kuiper belt objects: a review
... It is apparent from Fig. 2 that the resonant populations are quite prominent, as is the population of SDOs and the non-resonant population of the classical KBOs. Overall, the resonant KBOs are roughly one-third of the ...

Testing substellar models with dynamical mass measurements
... Finally, a large sample of ultracool binary orbits will provide constraints on formation models for low-mass stars and brown dwarfs as the orbital parameters of binaries (e.g., semimajor axis and ...

The fate of exomoons in white dwarf planetary systems
... planets repeatedly perform discontinuous jumps in semimajor axis. Because the integrations took place on the white dwarf phase, it was not necessary to take stellar evolution into consideration. Note that ...

Characteristics of planetary candidates observed by Kepler. II. Analysis of the first four months of data
... Comparisons of the distributions presented in Figure 16 with previous figures show that they are similar to those for the ensemble of all candidates. The number versus orbital period is very much like that seen in Figure ...

Towards a population synthesis model of self gravitating disc fragmentation and tidal downsizing II : the effect of fragment fragment interactions
... Rerunning the model using the N-body integrator has a profound effect on the resulting population. While the overall destruction rate is around 40 per cent whether N-body physics is active or otherwise, fragment–fragment ...
