Symposium “The Periodic Table Through Space and Time’’
The Periodic Table Through Space and Time
(10 – 13 September, 2019, St. Petersburg)
The 2019 year is claimed as the International Year of the Periodic Table of Chemical Elements. This initiative was supported by many international organizations, including the International Astronomical Union (IAU). In September 9-13 of 2019, Saint-Petersburg (Russia) hosts the XXI Jubilee Mendeleev Congress on General and Applied Chemistry (http://mendeleev2019.ru/index.php/en/).
During this Congress, in Sept. 10-13 of 2019, we hold the Symposium “The Periodic Table Through Space and Time’’.
The basic law of the Universe is that it is constantly changing.These changes have been going on for almost 13.8 billion years. All the properties of the Universe: structural, thermal, ionization and, of course, chemical, were and are evolving. In the first few minutes during the Big Bang nucleosynthesis the first chemical elements appeared in the Universe: hydrogen and helium with a very small admixture of lithium. To compile the first Periodic Table only few cells would suffice but cosmologists are interested in this table, since the abundance of these very first chemical elements is a critical test of cosmological theories.
In about a hundred of millions of years, when the first stars have appeared, the process of nuclear fusion began in their bowels and as a result we got such an amazing variety of chemical elements. Part of this wealth is forever buried in the depths of extinct stars, but a significant fraction was expelled into space as a result of mass loss by stars and in grandiose stellar explosions. These elements came into interstellar matter (gas and dust), which new stars and planets were formed out. Astrophysicists use very sophisticated observational and theoretical techniques to understand what chemical elements the stars and the interstellar matter are composed of and how the great cycle of chemical production and exchange is working in space. The Periodic Table helps them very much. Now it contains 118 elements. Eighty stable elements and four radioactive elements are considered primordial, i.e. of space origin. The remaining 34 were discovered after they were produced synthetically.
The variety of chemical elements has caused the development of various processes of formation and destruction of compounds of chemical elements. i.е. molecules. One of the most important results of the chemical evolution (for us, not for the Universe itself) was the appearance of living beings that are trying to understand how it all happened. Astrochemists are studying the cosmic sources of the origin of about 200 molecules (and 400 molecular isotopologues) observed in space, including the most important organic compounds and very complex chemical processes in space. Ultimately, to understand the origin of life, this knowledge can be decisive.
At this Symposium leading cosmologists, astrophysicists and astrochemists are to define the current state of the issues presented above and exchange in new ideas and prospects. Celebration of 150-th anniversary years of the Periodic Table of chemical elements is a very important step in scientific progress that will never stop.
Main topics of the Symposium are:
— Big Bang and stellar nucleosynthesis
— Chemical evolution of the Universe: observations and models
— Elemental abundances: a key to stellar physics
Invited speakers: to be confirmed.
