Measuring Apsidal Clustering
Amir Siraj, Christopher F. Chyba, Scott Tremaine
The decade-long debate over the existence of apsidal clustering in the outer solar system is poised for reignition given the plethora of distant trans-Neptunian object (TNO) discov…
The Inner Kernel of the Classical Kuiper Belt
Amir Siraj, Christopher F. Chyba, Scott Tremaine
The `kernel' of the classical Kuiper belt was discovered by Petit et al. (2011) as a visual overdensity of objects with low ecliptic inclinations and eccentricities at semimajor ax…
Limits on Stellar Flybys in the Solar Birth Cluster
Amir Siraj, Christopher F. Chyba, Scott Tremaine
The orbits of small bodies in the outer solar system are particularly sensitive to gravitational perturbations, including stellar flybys. Stellar clusters, with low velocity disper…
Measuring the Mean Plane of the Distant Kuiper Belt
Amir Siraj, Christopher F. Chyba, Scott Tremaine
In the absence of any unseen planetary-mass bodies in the outer solar system, the mean plane of the distant Kuiper belt should be the same as the plane orthogonal to the angular mo…
Orbit of a Possible Planet X
Amir Siraj, Christopher F. Chyba, Scott Tremaine
The plausibility of an unseen planet in the outer solar system, and the expected orbit and mass of such a planet, have long been a topic of inquiry and debate. We calculate the lon…
Shrinking binary and planetary orbits by Kozai cycles with tidal friction
Daniel Fabrycky, Scott Tremaine
At least two arguments suggest that the orbits of a large fraction of binary stars and extrasolar planets shrank by 1-2 orders of magnitude after formation: (i) the physical radius…
Apsidal Alignment in Upsilon Andromedae
E. I. Chiang, S. Tabachnik, S. Tremaine
One of the parameters fitted by Doppler radial velocity measurements of extrasolar planetary systems is omega, the argument of pericenter of a given planet's orbit referenced to th…
The geometry of phase mixing
S. Tremaine
Partially phase-mixed structures in galaxies occupy a complex surface of dimension D in six-dimensional phase space. The appearance of such structures to observers is determined by…
