ИСТИНА

Infrared sky surveys carried out by the modern space telescopes Spitzer and WISE led to the discovery of a large variety of circum- and interstellar nebulae around massive stars. The high angular resolution of these surveys allowed us to see the fine structure of newly discovered and previously known nebulae, which leads to the need for modification or revision of models of their formation. In this presentation, I will discuss the possible role of variable mass loss in interacting binary systems, stellar and interstellar magnetic fields, and circumstellar disks in the formation of the observed morphological diversity of nebulae produced by runaway stars.
