Query: The Resonant Transneptunian Populations   The transneptunian objects (TNOs) trapped in mean-motion resonances with
Neptune were likely emplaced there during planet migration late in the
giant-planet formation process. We perform detailed modelling of the resonant
objects detected in the Canada-France Ecliptic Plane Survey (CFEPS) in order to
provide population estimates and, for some resonances, constrain the complex
internal orbital element distribution. Detection biases play a critical role
because phase relationships with Neptune make object discovery more likely at
certain longitudes. This paper discusses the 3:2, 5:2, 2:1, 3:1, 5:1, 4:3, 5:3,
7:3, 5:4, and 7:4 mean-motion resonances, all of which had CFEPS detections,
along with our upper limit on 1:1 Neptune Trojans (which is consistent with
their small population estimated elsewhere). For the plutinos (TNOs in the 3:2
resonance) we refine the orbital element distribution given in Kavelaars et al.
(2009) and show that steep H-magnitude distributions (N(H) proportional to
10aH, with a=0.8-0.9) are favoured in the range Hg=8-9, and confirm that this
resonance does not share the inclination distribution of the classical Kuiper
Belt. We give the first population estimate for the 5:2 resonance and find
that, to within the uncertainties, the population is equal to that of the 3:2
(13,000 TNOs with Hg < 9.16), whereas the 2:1 population is smaller by a factor
of 3-4 compared to the other two resonances. We also measure significant
populations inhabiting the 4:3, 5:3, 7:3, 5:4, 7:4, 3:1, and 5:1 resonances,
with Hg < 9.16 (D >100 km) populations in the thousands. We compare our
intrinsic population and orbital-element distributions with several published
models of resonant-TNO production; the most striking discrepancy is that
resonances beyond the 2:1 are in reality more heavily populated than in
published models.
