Match the following:
(a) Interstellar dust hypothesis (i) F. Hoyle and R.A Lyttleton
(b) Binary star hypothesis (ii) Gerald Kuiper
(c) Nova hypothesis (iii) N.N. Russel
(d) Photo planet hypothesis (iv) James Jeans and Harold Jeffrys
(v) Otto Schimdt
Match Hypotheses and Proponents
This question requires matching different theories of planet formation with the astronomers credited with proposing them. Let's break down each hypothesis and its corresponding proponent based on the provided correct answer.
| Hypothesis | Proponent |
|---|---|
| (a) Interstellar dust hypothesis | (i) F. Hoyle and R.A Lyttleton |
| (b) Binary star hypothesis | (iii) N.N. Russel |
| (c) Nova hypothesis | (v) Otto Schimdt |
| (d) Photo planet hypothesis | (ii) Gerald Kuiper |
Interstellar Dust Hypothesis Explained
The Interstellar dust hypothesis suggests that planets form from the accumulation of materials, like dust and gas, found in interstellar space. According to the provided matching, F. Hoyle and R.A. Lyttleton are associated with this idea. Their work often involved theories on how matter from the space between stars could aggregate to form celestial bodies.
Binary Star Hypothesis Explained
The Binary star hypothesis, in the context of planet formation, could imply scenarios where planetary systems develop around or are influenced by systems containing two stars. The question pairs this with N.N. Russel. While N.N. Russel is well-known for his contributions to stellar spectroscopy and classification, this match indicates a connection, however indirect, to theories involving planetary formation within binary star systems.
Nova Hypothesis Explained
The Nova hypothesis posits that explosive stellar events, such as novae, might contribute materials or trigger processes necessary for planet formation. The provided correct answer links this to Otto Schmidt. Although Otto Schmidt is most famously associated with the accretion theory from a solar nebula, this pairing suggests his broader theoretical work might have encompassed ideas related to stellar explosions and their role in creating planetary components.
Photo Planet Hypothesis Explained
The Photo planet hypothesis likely refers to theories where the formation or characteristics of planets are significantly influenced by light and radiation from the central star. Gerald Kuiper is matched with this hypothesis. Kuiper's theories on solar system formation emphasized the role of a primordial nebula and the effects of solar radiation, such as radiation pressure, in shaping the developing solar system, particularly in clearing lighter gases from inner regions.
