The effect of interstellar matter on climatic variation

  author={Fred Sir Hoyle and Raymond Arthur Lyttleton},
The effect of interstellar matter on the sun's radiation is considered with a view to explaining changes in terrestrial climate. It appears that a star in passing through a nebulous cloud will capture an amount of material which by the energy of its fall to the solar surface can bring about considerable changes in the quantity of radiation emitted. The quantity of matter gathered in by the star depends directly on the density of the cloud and inversely on the cube of its velocity relative to… 
Frequency of nearby supernovae and climatic and biological catastrophes
MCCREA1,2 has proposed that the encounter of the Solar System with a dense cloud of interstellar material during its passage through a spiral arm of the Galaxy may produce such climatic catastrophes
Consequences of a past encounter of the earth with an interstellar cloud
In its motion through the galaxy the sun may have suffered a number of encounters with dense interstellar clouds for which the number density of molecular hydrogen H2 is > 10³ cm−3. Several authors
Glaciations and dense interstellar clouds
McCREA has revived the idea that the Earth's ice ages may have been caused by the interaction of the Sun with dense interstellar clouds1. In this theory, originally formulated by Hoyle and
Terrestrial mass extinctions, cometary impacts and the Sun's motion perpendicular to the galactic plane
Episodes of mass extinctions on the Earth are now strongly suspected to be cyclical1. We report here that our analysis of the data of Raup and Sepkoski1 suggests that the dominant cyclicity in major
Climatic effects during passage of the Solar System through interstellar clouds
IT seems likely that the Solar System passes through regions where there are a large number of dense interstellar clouds as the compression zone of the galactic spiral density wave passes the Sun.
McCrea’ has recalled the suggestion’ that terresterial Ice Ages may be produced by accretion of interstellar matter by the Sun. Subsequently several a ~ t h o r s j ~ have discussed further
Introduction In a paper published some months ago (1963) I tried to compare the supply and loss rates of dust in interplanetary space. The central thesis of the paper was that the Poynting-Robertson
Radiative effects in supersonic wind accretion onto gravitating objects
We investigate the influence of radiative effects on supersonic wind accretion onto gravitating objects. The accreting matter is assumed to be optically thin. The physical mechanisms taken into
The evidence for and against astronomical impacts on climate change and mass extinctions: a review
It is concluded that there is little evidence for intrinsic periodicities in biodiversity, impact cratering or climate on timescales of tens to hundreds of Myr, and the numerous assumptions and uncertainties involved in the interpretation of the geological data suggest that Galactic midplane and spiral arm crossings have little impact on biological or climate variation above background level.
