Star Formation in the Low Surface Brightness Galaxies: a Comparison with the Outer Regions of Normal Galaxies
Anatoly Zasov, Natalia Zaitseva, Anna Saburova
Low surface brightness galaxies (LSB-galaxies) and the outer regions of disks of "normal" surface brightness galaxies (HSB-galaxies) are compared in terms of the radial distributio…
Star formation in low-density regions of galactic disks
A. V. Zasov, N. A. Zaitseva, A. S. Saburova
We argue that star formation in the disks of low-surface-brightness (LSB) galaxies shares a similar nature with that occurring in the far outer regions of normal-brightness spiral…
Star formation in low brightness galaxies and in the extended gaseous disks of normal galaxies
Anatoly Zasov, Natalia Zaitseva, Anna Saburova
We analyze the available observational data on the radial distribution of gas and young stellar populations in the disks of low surface brightness (LSB) galaxies and in the outer r…
Formation of spiral dwarf galaxies: observational data and results of numerical simulation
Sergey Khrapov, Alexander Khoperskov, Natalia Zaitseva +2
Recent studies show the possibility of the formation of fairly regular and global spiral patterns in dwarf galaxies (dS type). Our sample of observed dwarf objects of this class al…
Galaxies with Abnormally High Gas Content in the Disk
Anatoly. V. Zasov, Natalia. A. Zaitseva
The content of gas in galaxies with an anomalously high relative mass of hydrogen for a given mass of the stellar population (VHR-galaxies) is considered, using…
On the formation of spiral arms in dwarf galaxies
Anatoly V. Zasov, Alexander V. Khoperskov, Natalia A. Zaitseva +1
Spiral structure (both flocculent and Grand Design types) is very rarely observed in dwarf galaxies because the formation of spiral arms requires special conditions. In this work w…
