The Gum Nebula is a faint supernova remnant extending about 40°across the southern sky,potentially affecting tens of background pulsars.Though the view that the Gum Nebula acts as a potential scattering screen for ba...
Chemical elements in space can be synthesized by stellar nuclear reactors. Studying the dynamics of processes occurring in the stars introduces a concept of the ensemble-averaged stellar reactor. For future interstell...
The possibility of the life origin in the stellar systems, located at a distance of ~200 pc from the solar system, was investigated. The stars, in the spectrums of which C (carbon), O (oxygen), N (nitrogen), and P (ph...
The transition radiation of a charged particle crossing the interface of two media having a monatomic impurity layer is investigated. It is shown that at sliding angles of incidence of a particle on the boundary of th...

Density functional theory(DFT)is the most versatile electronic structure method used in quantum chemical calculations,and is increasingly applied in astrochemical research.This mini-review provides an overview of the ...
Interstellar scintillation(ISS)caused by scattering from electron density microstructure(?1 AU)provides unequaled spatial resolving power for a number of applications in astronomy.These include studies of the interste...

Using quantum chemical calculations,we model the pathways for synthesizing two purine nucleobases,adenine and guanine,in the gas-phase interstellar environment,surrounded by neutral atomic hydrogen(H I).H I is found a...
Space-based plasma(i.e.,a highly ionized gas or the fourth state of matter)blobs are isolated pockets of this highly ionized gas made up of charged particles.These blobs are believed to have a substantial impact on th...

China has planned and implemented a series of lunar and deep space exploration programs since the first lunar exploration satellite Chang’E-1 launched in 2007.In the future,China has initiated the international lunar...
Unidentified Infrared emission bands (UIBs) are infrared discrete emissions from circumstellar regions, interstellar media (ISM), star-forming regions, and extragalactic objects for which the identity of the emitting ...
