Planet-planet scattering best explains the eccentricity distribution of extrasolar giant planets. Past literature showed that orbits planets evolve due to planet-planet scattering. This work studies spin evolution in 2-planet systems. Spin can dramatically spin-orbit coupling made possible by evolving and orbital precession during phase. The main source torque planet is stellar torque, total pl...

THE FIRST points to be considered in a study of peripheral vision are whether light can reach the periphery at all; and, if so, whether it suffers any loss of intensity as compared with the light reaching the fovea, and also whether the dioptric system is capable of producing a good image with the light which reaches the periphery. The reduction in intensity due to light-absorption in the media...

This feature, and weak spectral power in the prece...

In this work, we determined the analytical expressions of the form factor of a cubical particle in the WKB approximation. We adapted some variables (size parameter, refractive index, the scattering angle) and found the form factor in the approximation of Rayleigh-Gans-Debye (RGD), Anomalous Diffraction (AD), and determined the efficiency factor of the extinction. Finally, to illustrate our form...
