Whenever we study the properties of any celestial body - be it a planet or a star - all information we wish to gain can reach us through two different channels: their gravitational attraction, and their light. Gravitational interaction between our Earth and its celestial neighbours is, however, measurable only at distances of the order of the dimensions of our solar system; and the only means of communication with the realm of the stars are their nimble-footed photons reaching us - with appropriate time-lag - across the intervening gaps of space. As long as a star is single and emits constant light, it does not constitute a very revealing source of information. A spectrometry of its light can disclose, to be sure, the temperature (colour, or ionization) of the star‘s semi-transparent outer layers, their chemical composition, and prevalent pressure (through Stark effect) or magnetic field (Zeeman effect), it | | 出版日期 | Book 1979 | | 关键词 | Inclined Orbit; celestial bodies; earth; gravitation; gravity; planet; solar system; spectrometry; star; star | | 版次 | 1 | | doi | https://doi.org/10.1007/978-94-009-9466-9 | | isbn_softcover | 978-90-277-1044-4 | | isbn_ebook | 978-94-009-9466-9Series ISSN 0067-0057 Series E-ISSN 2214-7985 | | issn_series | 0067-0057 | | copyright | D.
