Accretion disks form around the young stars, and this is where radiative feedback comes in. As young stars accrete mass, they heat up. They radiate this heat outward into their own accretion disks. As ...

Dr. JIAO Chengliang from Yunnan Observatories of the Chinese Academy of Sciences, collaborating with Prof. XUE Li's group from Xiamen University, performed three-dimensional (3-D) simulations of the ...

Stars form in massive clouds of gas called molecular clouds. As they form, they accrete gas from these clouds, and as the stars rotate, gas and dust accumulates in a rotating disk around the star ...

A model of ultraviolet and optical emission from the tidal disruption event AT 2018hyz is shown in this schematic diagram. As an accretion disk forms quickly after the TDE, it generates x-ray emission ...

Astronomers from the University of Amsterdam in the Netherlands have shown that forming massive stars are much bigger than grown-up massive stars. Their observations confirm the theory that, at the ...

Starting from the upper left and moving clockwise from large to small scales: upper left —"spiral-like" system; upper right — "bar-like" structure; lower right — rotating infalling envelope; lower ...
