Query: Beyond the Kuiper Belt Edge: New High Perihelion Trans-Neptunian Objects
  With Moderate Semi-major Axes and Eccentricities   We have been conducting a survey for distant solar system objects beyond the
Kuiper Belt edge (~50 AU) with new wide-field cameras on the Subaru 8 meter and
CTIO 4 meter telescopes. We are interested in the orbits of objects that are
decoupled from the giant planet region in order to understand the structure of
the outer solar system, including whether a massive planet exists beyond a few
hundred AU as first reported by Trujillo and Sheppard (2014). In addition to
discovering extreme trans-Neptunian objects detailed elsewhere, we have found
several objects with high perihelia (q>40 AU) that differ from the extreme and
inner Oort cloud objects due to their moderate semi-major axes (50<a<100 AU)
and eccentricities (e<0.3). Newly discovered objects 2014 FZ71 and 2015 FJ345
have the third and fourth highest perihelia known after Sedna and 2012 VP113,
yet their orbits are not nearly as eccentric or distant. We found several of
these high perihelion but moderate orbit objects and observe that they are
mostly near Neptune mean motion resonances and have significant inclinations
(i>20 degrees). These moderate objects likely obtained their unusual orbits
through combined interactions with Neptune's mean motion resonances and the
Kozai resonance, similar to the origin scenarios for 2004 XR190. We also find
the distant 2008 ST291 has likely been modified by the MMR+KR mechanism through
the 6:1 Neptune resonance. We discuss these moderately eccentric, distant
objects along with some other interesting low inclination outer classical belt
objects like 2012 FH84 discovered in our ongoing survey.
