Families among high-inclination asteroids

High Inclination Planets and Asteroids in Multistellar Systems

The Kozai mechanism often destabilises high inclination orbits. It couples changes in the eccentricity and inclination, and drives high inclination, circular orbits to low inclination, eccentric orbits. In a recent study of the dynamics of planetesimals in the quadruple star system HD98800 (Verrier & Evans 2008), there were significant numbers of stable particles in circumbinary polar orbits ab...

The stable Kozai state for asteroids and comets With arbitrary semimajor axis and inclination

Semianalytical averaging is used to compute secular perturbations on the orbits of asteroids and comets; the method is applicable even for planet-crossing orbits. We prove that for every value of the asteroid/comet semimajor axis, and for an arbitrary number of perturbing planets, there is a stable region of orbits free from node crossings; it corresponds to either circulation or libration of t...

Inequality Among American Families

From 1975 to 2005, the variance in incomes of American families with children increased by two-thirds. Labor market studies of the growth in inequality emphasize the rising pay of college graduates, while demographers study changes in family structure. We join these lines of research by viewing income inequality as the product of the distribution of earnings in the labor market and the pooling ...
