The Ophiuchus Superbubble is an astronomical phenomenon located in the
Structure
The movable 110 meter antenna of a radio telescope made it possible to take pictures of several neighboring regions of the sky, resulting in a folded mosaic in which an area filled with hydrogen was highlighted. Near this area the interstellar gas is disturbed and many ejections are evident.
The total mass of HI in the system is ≈ 106
Geographical
The superbubble is located 23 thousand light-years from the Earth, and the object itself is "raised" 10 thousand light-years above the plane of the galaxy.
According to the Kompaneets model of an expanding bubble, the age of this system is ≈ 30 Ma, and its total energy content is ~ 10^53 erg. It may be at the stage when expansion stops and the shell begins to experience significant instabilities. This system offers an unprecedented opportunity to study several important phenomena at close range, including the evolution of superbubbles, turbulence in the HI shell, and the magnitude of the ionizing flux over the galactic disk.
Formation hypothesis
The
Such structures are capable of influencing the distribution of chemical elements in the galaxy: heavy nuclei that are born inside stars are ejected during an explosion together with gas, which - in the form of a "superbubble" - transports them over considerable distances.[2]
