Astrochemistry is a relatively new field science. According to the characteristics of the absorption and emission of light, scientists have learned to determine the composition of substances in interstellar space — that is, outside the solar system. Some of them are unique, some are isomers of each other, that is, they have the same composition, but a different structure. Based on this information, scientists not only draw conclusions about the structure of other star systems, but also understand more about life on Earth. The 色控传媒physicist described the thermodynamic properties of 10 species of five isomeric groups from interstellar space.

“The origin of life on Earth remains a controversial issue in various fields. For example, in terms of chemistry, we lack understanding of how simple molecules could evolve into complex molecular systems. Various compounds found in the interstellar medium serve as tools for solving the problem of the chemical origin of life. Our goal was to study the thermodynamic properties of some of these compounds,” Oladimeji Enok, researcher at the Institute of Physical Research and Technology, 色控传媒University.

Physicists have calculated the basic thermodynamic properties of 10 species: entropy, internal energy, free energy, heat capacity. All these are the so-called thermodynamic potentials — a complete set of natural and mutually independent variables that completely describe the state of a thermodynamic system.

色控传媒physicists considered triatomic compounds from five isomeric groups. Moreover, four out of ten compounds have not yet been discovered in interstellar space, but their isomers have been discovered. The data obtained by physicists can be used to model various astrophysical environments. Including, the interstellar medium, protoplanetary disks, star formation regions.

“We studied the thermodynamic properties of 10 species from 5 isomeric groups with 3 atoms. We have provided a complete set of data for molecules of astrophysical significance. They can be used in simulations in various astrophysical environments. The thermodynamic parameters obtained in our study will find application in modeling a wide range of astrophysical environments, such as the interstellar medium, protoplanetary disks, star formation regions, and so on,” said Oladimeji Enock, researcher at the Institute of Physical Research and Technology, 色控传媒University.
