Sites of star formation in the tidal structures
Anatoly Zasov, Anna Saburova, Oleg Egorov
TL;DR
This paper reviews recent observations of star formation sites in tidal structures of interacting galaxies, highlighting their diverse properties and the mechanisms that trigger star formation in these unique environments.
Contribution
It provides a comparative analysis of star-forming regions in tidal structures across multiple galaxy systems using spectroscopic observations.
Findings
Star formation sites vary significantly in properties across different systems.
Chemical abundances and dynamics differ among the observed regions.
The mechanisms driving star formation in tidal structures are diverse.
Abstract
We give a short review of the current results of studying of star formation sites observed beyond the main discs of galaxies in different interacting systems: Arp 270, Arp 194, Arp 305, NGC 4656 and NGC 90. The observations were carried out at the 6-meter telescope BTA in SAO RAS with the SCOPRPIO-2 spectrograph. The properties of star forming islands, their mass, dynamics, chemical abundances, their possible fate and the mechanisms inspiring star formation, appear to be different in different systems.
