Eccentricity Evolution for Planets in Gaseous Disks [PDF]
, 2002 We investigate the hypothesis that interactions between a giant planet and the disk from which it forms promote eccentricity growth. These interactions are concentrated at discrete Lindblad and corotation resonances.

The dynamical evolution of massive black hole binaries - I. Hardening in a fixed stellar background [PDF]
, 1996 The stellar ejection rate and the rates of change of the binary semimajor axis and eccentricity are derived from scattering experiments for the restricted three-body problem.

Effect of Installation Error on Rotary Seal of Aero Engine
Aerospace, 2022 The rotary seal is a key component of the aero engine. Under actual working conditions, most rotary seals always operate in an eccentric state (caused by installation errors), and when a large eccentricity occurs, it may lead to a large amount of gas ...

Eccentricity in Induction Machines—A Useful Tool for Assessing Its Level
Energies, 2021 In the condition monitoring of induction machines operating in various industry sectors, the assessment of eccentricity is as important as the assessment of the condition of windings, bearings, mechanical vibrations or noise.

Re-entry prediction of objects with low-eccentricity orbits based on mean ballistic coefficients
Open Astronomy, 2020 During re-entry objects with low-eccentricity orbits traverse a large portion of the dense atmospheric region almost every orbital revolution. Their perigee decays slowly, but the apogee decays rapidly. Because ballistic coefficients change with altitude,

Superhabitability of High-obliquity and High-eccentricity Planets
The Astrophysical Journal, 2023 Planetary obliquity and eccentricity influence climate by shaping the spatial and temporal patterns of stellar energy incident at a planet’s surface, affecting both the annual mean climate and magnitude of seasonal variability.

Universality of the saturation scale and the initial eccentricity in heavy ion collisions [PDF]
, 2006 Recent estimates that Color Glass Condensate initial conditions may generate a larger initial eccentricity for noncentral relativistic heavy ion collisions (relative to the initial eccentricity assumed in earlier hydrodynamic calculations) have raised ...

The Exoplanet Eccentricity Distribution from Kepler Planet Candidates [PDF]
, 2012 The eccentricity distribution of exoplanets is known from radial velocity surveys to be divergent from circular orbits beyond 0.1 AU. This is particularly the case for large planets where the radial velocity technique is most sensitive.

Discovery of the strongly eccentric, short-period binary nature of the B-type system HD 313926 by the MOST satellite [PDF]
, 2007 The MOST photometric space mission discovered an eclipsing binary among its guide stars in June 2006 which combines a relatively large eccentricity e = 0.20 with an orbital period of only 2.27 days. HD 313926 appears to consist of two early-type stars of
