Eccentric Behavior of Disk Galaxies
The Astrophysical Journal, 1999 A theory is developed for the dynamics of eccentric perturbations $[\propto \exp(\pm i )]$ of a disk galaxy residing in a spherical dark matter halo and including a spherical bulge component. The disk is represented as a large number $N$ of rings with shifted centers and with perturbed azimuthal matter distributions.

Stability and Formation of the Resonant System HD 73526 [PDF]
, 2007 Based on radial velocity measurements it has been found recently that the two giant planets detected around the star HD 73526 are in 2:1 resonance. However, as our numerical integration shows, the derived orbital data for this system result in chaotic ...

Approximating the inspiral of test bodies into Kerr black holes [PDF]
, 2002 We present a new approximate method for constructing gravitational radiation driven inspirals of test-bodies orbiting Kerr black holes. Such orbits can be fully described by a semi-latus rectum $p$, an eccentricity $e$, and an inclination angle $\iota ...

Cortical and behavioral sensitivity to eccentric polar form
Journal of Vision, 2011 Patterns composed of local features aligned relative to polar angle, yielding starbursts, concentric circles, and spirals, can inform the understanding of spatial form perception. Previous studies have shown that starburst and concentric form instantiated in Glass patterns are, relative to spirals, both more readily detected in noise and evoke higher ...

Eccentric Behaviors of the Brownian Sheet Along Lines
The Annals of Probability, 2002 The Brownian sheet is a centered, continuous Gaussian random field \(W(t),\) \(t\in \mathbb R^2\), indexed by the positive quadrant in the plane, with covariance given by \(E W(s_1,s_2)W(t_1,t_2)=(s_1\wedge t_1) (s_2\wedge t_2)\). It is one of the natural extensions of Brownian motion to higher dimensional time.

Determination of new coefficients in the angular momentum and energy fluxes at infinity to 9PN for eccentric Schwarzschild extreme-mass-ratio inspirals using mode-by-mode fitting [PDF]
, 2020 We present an extension of work in an earlier paper showing high precision comparisons between black hole perturbation theory and post-Newtonian (PN) theory in their region of overlapping validity for bound, eccentric-orbit, Schwarzschild extreme-mass ...
