Contribution of the Earth's gravitational potential to variations in orbital motion of short-period comets
《Research in Astronomy and Astrophysics》2016年第4期1-6,共6页Valentina M.Chepurova Nelli V.Kulikova Elena N.Petrovskaya 
We present simulation results on evolution development of orbital motion of short-period comets with the revolution period not exceeding 6-7 years, namely comets 21P/Giacobini-Zinner, 26P/Grigg- Skjellerup and 7P/Pons...

The Exolife: Gas Dust Streams and Seeds
《Journal of Earth Science and Engineering》2015年第3期203-214,共12页Oleg B. Khavroshkin Vladislav V. Tsyplakov 
The hypothesis that bacteria and protozoa microorganisms are able to travel from one planet to another and become of exolife was not taken seriously by the scientific community for a long time. However at the end of t...
