Researchers using high-resolution 3D simulations on powerful supercomputers found that stellar rotation greatly enhances the mixing of elements from a star’s core to its surface, explaining observed chemical changes in red giants; rotating stars mix materials over 100 times faster than non-rotating ones, revealing rotation as a key driver of stellar evolution and informing predictions for the Sun’s future.
Supermassive black holes may feed much faster than previously thought, according to new 3D simulations. These simulations suggest that black holes can consume gas and dust from surrounding accretion disks over a matter of months, rather than hundreds or thousands of years. The findings could help scientists understand how black holes consume surrounding material and how this process affects the evolution of galaxies. The simulations also indicate that the feeding process involves the tearing and replenishing of the inner part of the disk, which may explain the quick brightening and dimming observed in some quasars.
