- AB7 abstract "AB7, also known as SMC WR7, is a binary star, consisting of one Wolf-Rayet star, highly evolved massive star, and a mid-age massive companion of spectral type O. They orbit in a period of 19.7 daysThese exceptional stars have very strong stellar winds and they continuously eject energetic particles — like the "solar wind" from the Sun — but some 10 million to 1 billion times more intensely than our star. These powerful winds exert an enormous pressure on the surrounding interstellar material and forcefully shape those clouds into "bubbles", well visible in the photos by their blue colour. AB7 is particularly remarkable: the associated huge nebula and He-II region indicate that this star is one of the hottest WR-star known so far, with a surface temperature in excess of 80,000 degrees. Just outside this nebula, a small network of green filaments is visible - they are the remains of another supernova explosion.".
