A new analysis of the common accretion-disk model explaining how planets form in a debris disk around our Sun uncovered a possible reason for Earth's comparative dryness. The study found that our ...

Astronomers from the Raman Research Institute (RRI) probed a rare signal from a bright X-ray source, which is repeating — though not at a neat, fixed rate — to reveal that its wobbling accretion ...

Through the study of the optical to extreme ultraviolet radiation generated by the accretion of supermassive black holes at the centers of quasars, Associate Professor Cai Zhenyi and Professor Wang ...

Tilted accretion disc model Artist’s impression of the black hole at the centre of M87, showing how the accretion disc and jet are misaligned with the rotational axis of the black hole. (Courtesy: ...

Observations of the interacting binary star using telescopes at Kitt Peak National Observatory and NASA’s Spitzer Space Telescope suggest that the disks of hot gas that accumulate around a wide ...

Associate Professor CAI Zhenyi and Professor WANG Junxian from the Department of Astronomy at the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS), through ...

The black hole’s spin axis is assumed to align vertically. The jet’s direction is almost perpendicular to the disk. The misalignment between the black hole spin axis and the disk rotation axis ...
