This chapter discusses the origin of the solar system and the Hoyle's theory. The solar system theories can be divided into two classes: (1) nebular theories and (2) encounter-capture theories. Hoyle gave an explanation of the very striking fact that the Sun has very little angular momentum...
太阳系起源和演化理论新探索 New Probe into Origin and Evolution Theory of the Solar System 喜欢 0 阅读量: 106 作者:薛善夫,陈薛旸 摘要: 以往星云说,用可压缩流体的临界自转角速度公式去确定原始星云初始的角动量数值,是误导.因为原始星云转动快慢还不知道呢,怎么就把它当作临界自转去计算呢.本文推导出...
However, the capture theory has not gained as much widespread acceptance as the nebular theory due to the lack of evidence supporting the notion of planets being captured by the Sun. In conclusion, the origin of the solar system has been a subject of scientific inquiry for many years. The ...

solar system-the Sun as well as all of the planets, satellites,asteroids, and comets—formed from a vast, rotating cloud of gas and dust called the solarnebula. ln the modern version of their theory, the solar nebula is thought to have had a mass somewhat greater than that of our ...
Hannes Alfvèn and Gustaf Arrhenius 1976 Washington DC: NASA xii + 599 pp price $38About 10 years ago the authors of this book came together to combine their individual approaches into a single theory of the origin and evolution of the solar system. As would be expected, in various component...
The formation of the Solar System by Gravitational Instability. arXiv: astro-ph/0403376 The early gas–dust solar nebula is considered: the gasdynamic theory is used to study the gravitational Jeans-type instability in its protoplanetary disk. The implications for the origin of the solar system ar...
of a priori knowledge or constraints, if we do not assume a metric theory of gravitation or if we assume thatβ−1,η, or both parameters are equal to 0. These tests generalize our results further and are shown in Supplementary Table2. The Nordtvedt equation significantly benefits the ...
In conclusion, our analysis of Mercury’s ephemeris with the MESSENGER data enhances the knowledge of the relativistic parameterη, confirming predictions of Einstein’s theory of GR. We provide one of the first observations of the solar system expansion due to the solar mass loss. The negative ...
Forging the Planets: The Origin of Our Solar System Discusses the origin of the solar system. Astronomers' theory the Sun and planets were born from a rotating disk of cosmic gas and dust; Idea of a solar nebula formulated in 1755 by the Prussian philosopher and physicist Immanuel Kant; T....
