摘要:The flyby anomaly is a persistent riddle in astrodynamics. Orbital analysis in several flybys of the Earth since the Galileo spacecraft flyby of the Earth in 1990 have shown that the asymptotic post-encounter velocity exhibits a difference with the initial velocity that cann...

摘要:The cusp has important effects on the transportation of particles and their energy from the solar wind to the magnetosphere, and ionosphere, and high-altitude atmosphere. The cusp can be considered to be a part of the magnetospheric boundary layer with weaker magnetic fields. It ...

摘要:This paper analyzes the dynamical evolution of satellites formed by two masses connected by a cable— tethered satellites . We derive the Lagrangian equations of motion in the neighborhood of the collinear equilibrium points, especially for the \(L_{2} \) , of the restricted ...

摘要:Innovated by the nonlinear modes concept in the vibrational dynamics, the vertical periodic orbits around the triangular libration points are revisited for the Circular Restricted Three-body Problem. The \(\zeta \) -component motion is treated as the dominant motion and the \(\xi...

摘要:The low-thrust propulsion will be one of the most important propulsion in the future due to its large specific impulse. Different from traditional low-thrust trajectories (LTTs) yielded by some optimization algorithms, the gradient-based design methodology is investigated for LTT...

摘要:Dust growth and settling, as an initial step of planet formation in protoplanetary disks, have an important impact on the appearance of the spectral energy distribution (SED). Selecting a promising sample of disks with signs of these processes helps to guide future observati...

摘要:In this article we propose a model for the Pulsar J0348+0432 (Antoniadis et al. in Science 340:1233232, 2013 ) in a compact relativistic binary. Here we investigate the physical properties of the Pulsar J0348+0432 by using the Finch and Skea (Class. Quantum Gravity 4:467, 1989 ) ...

摘要:We have studied the time dependence of the gravitational constant \(G\) and cosmological constant \(\varLambda\) by taking into account an anisotropic and homogeneous Bianchi type-I space-time in the framework of the modified \(f(R,T)\) theory of gravity proposed by Harko et al. ...

摘要:In this paper, we show that black holes with PMI source exhibit the \(T\) – \(S\) criticality and derive the relevant critical physical quantities analytically. The values of critical quantities for the case \(s\neq1\) vary from those for the case \(s=1\) , showing the effec...

摘要:Spectral energy distribution (SED) fitting of stellar population synthesis models is an important and popular way to constrain the physical parameters—e.g., the ages, metallicities, masses for stellar population analysis. The previous works suggest that both blue-bands and r...
