THE SOLAR SYSTEM AS AN EXOPLANETARY SYSTEM [PDF]

open access: yesThe Astrophysical Journal, 2015
With the availability of considerably more data, we revisit the question of how special our Solar System is, compared to observed exoplanetary systems. To this goal, we employ a mathematical transformation that allows for a meaningful, statistical comparison.

Formation and dynamics of a solar eruptive flux tube

open access: yesNature Communications, 2018
Solar eruptions are large explosions occurring in the solar atmosphere. Here, the authors perform magnetohydrodynamic simulations to unveil the dynamics of a solar eruption, and find that these are dominated by nonlinear processes involving flux tube ...

The origin of the solar system [PDF]

open access: yesJournal of the Franklin Institute, 1924
The astronomer of to-day has at his disposal telescopes which range in aperture from his naked eye, of aperture about one-fifth of an inch, up to the giant Mount Wilson telescope of more than 100 inches. If we lived in the midst of a uniform infinite field of stars, or in a field which was uniform as far as our telescopes could reach, the numbers of ...

Optimal Design of Aperture Illuminations for Microwave Power Transmission with Annular Collection Areas

open access: yesEngineering, 2023
This work presents an optimal design method of antenna aperture illumination for microwave power transmission with an annular collection area. The objective is to maximize the ratio of the power radiated on the annular collection area to the total ...
