Common envelope evolution (CEE) is believed to be an important stage in the of binary/multiple stellar systems. Following this stage, CE thought ejected, leaving behind a compact binary (or merger product). Although extensively studied, CEE process still little understood, and although most binaries have non-negligible eccentricity, effect initial eccentricity on has been explored. Moreover, st...

We present spectroscopic and photometric observations of the eclipsing binary V32 located in the central field of the globular cluster NGC 6397. The variable is a single-line spectroscopic binary with an orbital period of 9.8783 d and a large eccentricity of e = 0.32. Its systemic velocity (γ = 20.7 km s) and metallicity ([Fe/H] ∼ -1.9) are both consistent with cluster membership. The primary c...

The existence of torsion, as well as consideration of the Soil-Structure Interaction (SSI), increase the natural periods of the structure resulting from a subsequent decrease in the seismic demand of the system. This paper summarizes the probabilistic assessment for evaluation of collapse fragility curves in concrete moment resisting structure with different mass center eccentricities. A 12-sto...

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. They are used to study the evolution of binaries in simple models for galactic nuclei, starting soon after the black holes become bound and continuing until the evolution is dominated by the emission of gravitational radia...

The known extrasolar planets exhibit many interesting and surprising features—extremely shortperiod orbits, high-eccentricity orbits, mean-motion and secular resonances, etc.—and have dramatically expanded our appreciation of the diversity of possible planetary systems. In this review we summarize the orbital properties of extrasolar planets. One of the most remarkable features of extrasolar pl...

Stellar-mass compact binaries in eccentric orbits are almost guaranteed sources of gravitational waves for Laser Interferometer Space Antenna. We present a prescription to compute accurate and efficient gravitational-wave polarizations associated with bound compact binaries of arbitrary eccentricity and mass ratio moving in slowly precessing orbits. We compare our approach with those existing i...

Abstract Thrust eccentricity refers to the phenomenon that thrust vector deviates from axis of symmetry. This will produce lateral force and torque around aircraft, which affects normal flight increases required control torque, reduces density uncontrolled rockets. There are three sources eccentricity: mass eccentricity, geometric aerodynamic eccentricity. The is caused by asymmetrical flow com...
