The dynamical tide can play an important role in the orbital motion of close eccentric double white dwarf binaries. As launching space-based gravitational-wave detector, Laser Interferometer Space Antenna (LISA), is just around corner, detection gravitational wave signals from such systems anticipated. In this paper, we discuss influence on orbits, focusing effect periastron precession. We show...

Abstract From estimates of the near-surface heat capacity planets it is shown that thermal timescale larger than orbital period in presence a global ocean well-mixed to depth 100 m, or an atmosphere with pressure several tens bars. As consequence, temperature fluctuations such on eccentric orbits are damped. The average should be calculated by taking temporal mean irradiation over orbit, which ...

Gravitational waves (GW) from eccentric binaries have intricate signals encoding important features about the location, creation and evolution of sources. Eccentricity shortens merger time, making emitted GW statistically predominant in observed data once detectors will reach required sensitivity. We present a novel implementation fully analytical templates binary black hole (BBH) mergers withi...

Due to the chaotic nature of the solar system, the question of its dynamic long-term stability can only be answered in a statistical sense, for instance, based on numerical ensemble integrations of nearby orbits. Destabilization of the inner planets, including catastrophic encounters and/or collisions involving the Earth, has been suggested to be initiated through a large increase in Mercury’s ...
