Theoretical models of planetary system formation: mass vs. semi-major axis [PDF]
, 2013 Context. Planet formation models have been developed during the past years to try to reproduce what has been observed of both the solar system and the extrasolar planets.

Advanced Functional Materials, EarlyView.The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.

Simulation of Contact Force of Fault Planetary Gear System based on Virtual Prototype Technology
Jixie chuandong, 2015 In order to obtain the changing pattern of contact force of fault planetary gear system,a dynamics model of fault planetary gear system is established and the computation method for contact force of gear meshing based on Hertz theory is also introduced ...

A detailed dynamical investigation of the proposed QS Virginis planetary system [PDF]
, 2013 In recent years, a number of planetary systems have been proposed to orbit-evolved binary star systems. The presence of planets is invoked to explain observed variations in the timing of mutual eclipses between the primary and secondary components of the

Saving Planetary Systems: Dead Zones and Planetary Migration [PDF]
The Astrophysical Journal, 2007 The tidal interaction between a disk and a planet leads to the planet's migration. A long-standing question regarding this mechanism is how to stop the migration before planets plunge into their central stars. In this paper, we propose a new, simple mechanism to significantly slow down planet migration, and test the possibility by using a hybrid ...

Advanced Functional Materials, EarlyView.This study demonstrates the use of a low‐cost 3D printing technique to prepare a large‐area PVDF‐FAPbI3 composite dielectric film for flexible TENG application. The δ→α phase transformation of the FAPbI3 nanofillers has significantly improved the β‐phase content, morphology, and dielectric properties of the PVDF film.

On the dynamical stability of the proposed planetary system orbiting NSVS 14256825 [PDF]
, 2013 We present a detailed dynamical analysis of the orbital stability of the two circumbinary planets recently proposed to orbit the evolved eclipsing binary star system NSVS 14256825. As is the case for other recently proposed circumbinary planetary systems

Planetary systems in a star cluster I: the Solar system scenario [PDF]
Monthly notices of the Royal Astronomical Society, 2019 Young stars are mostly found in dense stellar environments, and even our own Solar system may have formed in a star cluster. Here, we numerically explore the evolution of planetary systems similar to our own Solar system in star clusters.
