In the course of the study, scientists created computer models that simulate the shock wave near Zeta Smeenasz. Then they compared models with observations in infrared, visible and X-ray. Of the three models, two predicted that the brightest area of X-ray radiation should be on the edge of the shock wave near the star. This coincided with observations.
The problem is that all three models also predicted that X-rays should be weaker than observed, so none of the models are fully accurate, but these models are difficult to do well, and this work is a good first step, and scientists point out.
Zeta Snakestar had an interesting life. In the past, she was a typical big star, about 20 times more massive than the Sun. She was spinning around a big star company until the "partner" became supernova about a million years ago. The explosion threw away the Snake Bearer and now it's carrying the interstellar space.
The supernova also threw out the outer layers of the Companion star, so instead of the empty space, Zeta the Snake carrier runs through the residual gas, which is difficult, but thanks to this, astronomers have an extensive subject for research and beautiful photographs like on the cover.
Through interstellar gas, the star created heated shock waves that light on all wave lengths, from infrared to X-ray radiation. The physics of these shock waves is very complex and controlled by a set of mathematical equations of magnetohydrodynamics.
Modelling these equations is not an easy task, especially when a star has turbulence. Scientists already have an excellent view of the shock wave, so physics can easily compare observations to computer modelling.
