Where Does the Energy Go during the Interstellar NH3 Formation on Water Ice? A Computational Study

open access: yesThe Astrophysical Journal, 2023
In the coldest (10–20 K) regions of the interstellar medium, the icy surfaces of interstellar grains serve as solid-state supports for chemical reactions.

Interstellar Reddening Effect on the Age Dating of Population II Stars

open access: yesGalaxies, 2017
The age measurement of the stellar halo component of the Galaxy is based mainly on the comparison of the main sequence turn-off luminosity of the globular cluster (GC) stars with theoretical isochrones.

CLOUD STRUCTURE OF INTERSTELLAR MATTER. OBSERVATIONAL PARAMETERS

open access: yesOdessa Astronomical Publications, 2017
Parameters of 7600 HI clouds were determined on the base of HI RATAN-600 Survey in the second and third quadrants of galactic longitudes. The spectra of cloud linear diameters, HI densities and masses are obtained first for such huge population of clouds.

Stellar Bars in Isolated Gas-rich Spiral Galaxies Do Not Slow Down

open access: yesThe Astrophysical Journal, 2023
Elongated bar-like features are ubiquitous in galaxies, occurring at the centers of approximately two-thirds of spiral disks in the nearby Universe. Due to gravitational interactions between the bar and the other components of galaxies, it is expected ...

More than 30 000 volunteers involved in identification of tiny rare interstellar dust particle candidates collected by the Stardust mission

open access: yesHeidelberger Jahrbücher Online, 2017
The NASA Stardust mission returned the first tiny samples of interstellar dust from beyond the borders of our solar system. This region is almost devoid of matter and the interstellar dust particles floating through our solar system are extremely rare ...
