13. venera1e
The hotbed effect (hothouse effect) in the planets atmosphere is the inside atmosphere layers heating (of the Earth, Venus etc.), due to the transparent planet atmosphere for the main part of solar radiation (in optical range). In the atmosphere of the Earth this radiation is absorbed by the molecules of H2O, C02, O3 and others. ... As a result of human activities the CO2 content is increasing (and the other gases, absorbing in infrared range). ...

... The normal m 1 , c 1 indices and metallicities have been calculated for 2472 F-stars from the uvby and H fotometry. ... It is shown that the metallicity distribution of F6-G0 dwarfs is not a Gaussian one, but may be considered as a sum of two normal distributions. At the centre, the distribution shows a gap which subdivides all the stars into two metallicity groups. ...
