ALMA research team captures first clear image of accretion disk around a star
... radio telescope in Chile is the first clear image of an accretion disk – earlier technology was not able to obtain clear images. ALMA... years old, and take an image of its rotating accretion disk. ALMA, the most expensive radio telescope ever built, ...

Molecular oxygen detected for the first time in another galaxy
... their energy from material spiralling in towards an enormous black hole at the center of a galaxy forming a disk called an accretion disk. As the gas and dust spirals closer in, it accelerates and heats through gravitational and frictional forces...

Researchers probe black-hole mergers with fast-powered winds
...GRB have already been undertaken, with phenomena such as the afterglow emission of relativistic jets or strong disk winds in super-Eddington accretion disks have been postulated as the cause of this event. In order to shed more light on the turbulent...

Binary stars and their extraordinary lives
... between the two stars. Gas from the wind and bridge accumulates in an accretion disk around Mira B and collisions between rapidly moving particles in the disk produce X-rays. Pic (right): artist’s impression of the binary system. Similarly...
